Cancellation service n°1 in United Kingdom

Smarty Plus is a premium mobile network subscription service offered by Smarty, the UK's value-focused mobile virtual network operator that runs on the Three network infrastructure. After processing thousands of mobile network cancellations, I can tell you that Smarty Plus represents the network's enhanced tier, offering additional benefits beyond their standard SIM-only plans.
The service operates on a monthly rolling contract basis, which means you're not locked into lengthy commitments. This flexibility is actually one of Smarty's main selling points, though ironically, it's also what makes the cancellation process particularly important to understand properly. Keep in mind that even "flexible" contracts have specific procedures you must follow to avoid being charged for additional months.
From my experience handling mobile network terminations, people cancel Smarty Plus for several common reasons. Most frequently, customers find better value elsewhere, particularly when promotional periods end and the full monthly cost kicks in. Additionally, some discover that the Three network coverage doesn't meet their needs in their specific location, despite the network's generally good urban coverage. Others are consolidating family plans with different providers, or they're moving abroad and no longer need a UK mobile service.
Here's something important I've learned: many customers assume that because Smarty advertises "no contract" flexibility, they can simply stop paying and walk away. That's a costly mistake. You absolutely must follow the proper cancellation procedure, or you'll continue being charged, potentially damaging your credit rating if payments fail.
Before we dive into cancellation specifics, let me walk you through what you're actually cancelling. Understanding your plan details is crucial because it affects your notice period and final billing. I've seen countless cases where people didn't realise what they were paying for until they tried to cancel.
Smarty Plus builds upon Smarty's basic plans by adding premium features. The core service includes unlimited UK calls and texts, which is standard across most UK networks now. What sets Smarty Plus apart is the data allowance flexibility and additional perks like EU roaming with larger data allowances than basic plans.
The network operates on a monthly billing cycle, and here's where it gets interesting from a cancellation perspective: your billing date is set from when you first activated your SIM, not from the first of the month. This matters enormously when calculating notice periods, and it's something I'll cover in detail later.
| Data allowance | Monthly cost | Key features |
|---|---|---|
| Unlimited data | £20-25 | EU roaming, no speed caps, 5G included |
| 100GB | £15-18 | EU roaming, 5G where available |
| 50GB | £10-12 | Limited EU roaming, 4G/5G |
Most importantly, understand that Smarty Plus prices can vary based on promotional periods and when you joined. Check your latest bill or account dashboard for your exact pricing. This exact figure should be referenced in any cancellation correspondence to avoid disputes.
Smarty Plus typically includes data discount schemes where unused data generates account credits. When you cancel, you'll want to ensure any accumulated credits are properly settled. I've processed cases where customers lost £20-30 in credits simply because they didn't specifically mention these in their cancellation request.
The service also includes Wi-Fi calling and personal hotspot capabilities as standard. These features don't affect cancellation directly, but they're worth mentioning in your records to ensure complete service termination.
Now we're getting to the crucial part. After years of processing mobile network cancellations, I can tell you that understanding the terms of service isn't just recommended—it's essential for avoiding unexpected charges and complications.
Under UK consumer law, specifically the Consumer Contracts Regulations 2013, you have certain rights when cancelling services. For rolling monthly contracts like Smarty Plus, you're entitled to cancel at any time, but the provider can require reasonable notice. Smarty typically requires notice before your next billing cycle begins.
Here's a critical point many people miss: "reasonable notice" for mobile networks usually means you must cancel before your renewal date, not just before the end of your current paid period. If your billing date is the 15th of each month, and you cancel on the 14th, you might still be liable for the following month depending on when they process your request.
Smarty operates on a 30-day rolling contract basis. In practical terms, this means you need to provide cancellation notice that will be processed before your next automatic renewal. The safest approach I always recommend is to submit cancellation at least 10 working days before your billing date.
Keep in mind that Smarty processes cancellations during business hours only. If your cancellation letter arrives on a Friday afternoon, it might not be processed until Monday or Tuesday. This processing delay is exactly why I advocate for postal cancellation with tracking—you have proof of when they received it, regardless of when they processed it.
Smarty Plus operates on a "no refunds for partial months" basis, which is standard across UK mobile networks. If you've paid for the current month, you won't receive a pro-rata refund for unused days. However, you should continue to have service until the end of your paid period.
Additionally, any data credits or promotional discounts typically expire upon cancellation. Make sure you understand exactly what you're forfeiting before submitting your cancellation. I've seen customers rush to cancel only to realise they had £15 in data credits that disappeared.
| Timing of cancellation | Service continues until | Final charge |
|---|---|---|
| 10+ days before renewal | Current period end | Current month only |
| Less than 10 days before renewal | Possibly next period end | Risk of additional month charge |
| After renewal date | Following period end | Current month plus next month |
Let me share something I've learned from processing thousands of cancellations: postal cancellation with tracking is consistently the most reliable method for terminating mobile network subscriptions. Here's why this matters specifically for Smarty Plus.
Many customers naturally assume that cancelling online or through an app is more convenient. In theory, it should be. In practice, I've seen countless cases where online cancellations mysteriously "didn't process" or "weren't received." The customer has no proof, the company claims they never received the request, and suddenly you're arguing about charges for months you thought you'd cancelled.
With postal cancellation using Recorded Delivery or Special Delivery, you have independent proof from Royal Mail that your letter was delivered on a specific date. This isn't proof generated by the company's own systems—it's third-party verification. In disputes, this makes all the difference.
Under UK law, postal correspondence carries significant legal weight. A properly formatted cancellation letter, sent via tracked mail, creates a clear paper trail that courts recognise. I've seen cases where customers successfully challenged wrongful charges specifically because they had Royal Mail tracking evidence.
Most importantly, companies must acknowledge and process postal cancellation requests. They can't claim "we don't accept cancellations by post" because UK consumer protection regulations require them to provide accessible cancellation methods, and post is considered a fundamental communication channel.
Now, I understand that postal cancellation sounds old-fashioned and potentially time-consuming. This is where services like Postclic become genuinely useful. Rather than spending time formatting letters, finding the correct address, purchasing tracking services, and visiting the post office, Postclic handles the entire process digitally.
You provide your cancellation details through their platform, and they print, format, and send your letter via tracked Royal Mail services. You receive digital proof of postage and delivery, which you can save indefinitely. From my perspective as someone who values efficiency, this combines the legal reliability of postal cancellation with the convenience of digital services.
Additionally, Postclic ensures your letter is professionally formatted and includes all necessary details that companies require. I've seen poorly formatted cancellation letters rejected on technicalities, forcing customers to restart the process and potentially incurring additional monthly charges.
Right, let's walk through the actual cancellation process step by step. I'm going to share exactly how to do this properly, including the insider details that prevent common problems.
First, collect these essential details before writing anything. Having this information ready prevents delays and ensures your letter contains everything Smarty needs to process your cancellation immediately:
Keep in mind that mismatched information is one of the most common reasons cancellation requests get delayed. If your address on the cancellation letter doesn't match their records, they may reject it for security reasons.
Your cancellation letter needs to be clear, complete, and unambiguous. Here's what must be included, based on what actually gets cancellations processed smoothly:
Start with your personal details at the top: full name, address, mobile number, and account number. Make it easy for them to identify your account immediately. Next, include the date you're writing the letter—this establishes your notice period.
In the main body, state clearly and directly: "I am writing to cancel my Smarty Plus mobile service." Don't be vague or use phrases like "I'm thinking of cancelling" or "I'd like to discuss cancellation." Be definitive.
Specify when you want the cancellation to take effect. I recommend stating: "Please cancel my service at the end of my current billing period on [specific date]." This removes any ambiguity about timing.
Additionally, request written confirmation of your cancellation. State explicitly: "Please confirm this cancellation in writing to my address above, including confirmation that no further charges will be applied after [end date]."
Most importantly, mention any account credits, data discounts, or promotional balances, and request confirmation of how these will be settled. Don't assume they'll automatically handle this.
This is absolutely critical. You must send your cancellation to the correct address, or it will be delayed or potentially lost entirely. Here's the exact address for Smarty correspondence:
Double-check this address before sending. Address errors are surprisingly common and can add weeks to your cancellation timeline, potentially resulting in additional charges.
Never send cancellation letters via standard post. Always use tracked services. Here are your options and my recommendations:
Recorded Delivery (Royal Mail Signed For): This costs around £1.85 on top of normal postage and requires a signature on delivery. You get tracking and proof of delivery. This is the minimum level I recommend for any cancellation.
Special Delivery Guaranteed by 1pm: This costs approximately £6.85 and guarantees next-day delivery with full tracking and signature. Use this if you're close to your billing date and need certainty about delivery timing.
Keep in mind that the tracking number is your insurance policy. Save it, along with the proof of postage receipt, until your cancellation is confirmed and you've verified no further charges appear on your bank account.
Once Smarty receives your letter, here's what typically happens, based on standard processing timelines:
Within 2-3 working days, they should open and log your cancellation request. Your account will be flagged for termination. However, you likely won't receive immediate confirmation at this stage.
Within 5-7 working days, you should receive written confirmation of your cancellation. This confirmation should state your final billing date and confirm no further charges will be applied. If you don't receive this within 10 working days, follow up immediately.
Your service will continue until the end of your paid period. Don't be alarmed if your phone still works after they've confirmed cancellation—this is normal. The service should terminate at midnight on your final billing date.
Additionally, check your bank account or payment method 2-3 days after your final billing date to ensure no further direct debits or card charges have been attempted. If you see unexpected charges, contact your bank immediately to reverse them and reference your cancellation proof.
Documentation is everything in cancellation disputes. Here's exactly what to keep and for how long:
Keep your proof of postage receipt indefinitely—scan it or photograph it for digital backup. This small slip of paper is worth its weight in gold if disputes arise.
Save your Royal Mail tracking information, including screenshots showing delivery confirmation with the date and time. Take these screenshots within a few days of delivery, as Royal Mail tracking data eventually expires from their online system.
Keep copies of your actual cancellation letter. If you're using a service like Postclic, they typically provide PDF copies automatically, which is another significant advantage.
Most importantly, retain all confirmation correspondence from Smarty, including the written cancellation confirmation. Keep these documents for at least 12 months after cancellation, as billing disputes can sometimes emerge months later.
Let me share the insider knowledge I've accumulated from years of handling these cancellations. These tips prevent the most common problems I see repeatedly.
The single most important factor in smooth cancellations is timing. Never wait until the last minute. I recommend submitting your cancellation at least 14 days before your billing date, even though the minimum notice period is technically shorter.
Here's why this matters: if there are any problems with your letter—wrong address, insufficient information, processing delays—you have time to correct them before your renewal date. Cutting it close means any small problem results in paying for an additional month.
Additionally, avoid cancelling during peak periods if possible. The end of the month and the days immediately after Christmas see processing delays across most customer service departments. If your billing date falls during these periods, submit your cancellation even earlier.
Once your tracking shows delivery, wait 3-4 working days, then follow up. Don't wait for them to contact you. Here's the approach that works:
Contact Smarty customer service through their online chat or social media channels (not for cancellation itself, but for confirmation). Reference your cancellation letter sent by post, provide the tracking number and delivery date, and ask them to confirm it's been logged on your account.
This follow-up serves two purposes: it ensures your letter hasn't been overlooked, and it creates an additional record of your cancellation request. If they claim they haven't received it, you have your tracking proof showing delivery, which immediately escalates the issue to a supervisor level.
Even with perfect cancellation procedures, payment processing errors happen. Here's how to protect yourself:
Consider cancelling your direct debit or removing your payment card details after your final payment is due. However, only do this after your cancellation is confirmed and you're certain of your final payment date. Cancelling payment methods before your service ends can breach your contract and cause complications.
Set a calendar reminder for 2-3 days after your final billing date to check your bank account. If an unauthorised charge appears, contact your bank immediately to reverse it under the Direct Debit Guarantee or chargeback provisions. Provide them with your cancellation proof.
Keep in mind that some banks take 3-5 working days to process direct debits, so an expected charge might appear to post-date your cancellation. Check the actual transaction date, not just when it appears in your account.
Despite your best efforts, problems sometimes occur. Here's your escalation path:
First level: Contact Smarty customer service immediately, providing all your documentation. Most issues get resolved at this level if you have proper proof. Stay calm but firm, and always reference your tracking evidence.
Second level: If customer service doesn't resolve the issue within 48 hours, request escalation to their complaints team. Submit a formal complaint in writing (again, by tracked post), referencing your original cancellation and the problem you're experiencing.
Third level: If Smarty doesn't resolve your complaint within eight weeks, or if they issue a final response you're unhappy with, you can escalate to the Communications Ombudsman. This is a free service that investigates disputes between customers and communication providers. Your tracked postal evidence becomes crucial at this stage.
Let me warn you about the errors I see repeatedly, so you can avoid them:
Mistake one: Assuming online account closure cancels your service. Many people delete the Smarty app or close their online account and think that cancels their subscription. It doesn't. You must explicitly cancel the service itself through proper channels.
Mistake two: Porting your number to a new provider without cancelling Smarty. If you port your number out, Smarty should automatically cancel your service, but I've seen cases where they continue charging for the account even after the number's gone. Always submit formal cancellation even if you're porting.
Mistake three: Cancelling your payment method before cancelling the service. This doesn't cancel your subscription—it just means you're breaching your payment obligations. Smarty can pursue the debt and damage your credit rating. Always cancel the service first, then remove payment methods after your final bill is settled.
Most importantly, never assume silence means acceptance. If you don't receive written confirmation of your cancellation within 10 working days, chase it up aggressively. No news is not good news in cancellation situations.
While I've explained the complete manual process, there's no shame in using tools that make this easier. Services like Postclic exist specifically because postal cancellation, while reliable, can be time-consuming and inconvenient.
The advantage of using such services is that they eliminate the common errors: wrong addresses, missing information, inadequate tracking, poor letter formatting. They handle the physical posting process, which is particularly valuable if you work full-time and can't easily get to a post office during business hours.
Additionally, these services maintain digital records of everything, which is incredibly useful if you need to reference your cancellation months or even years later. Paper documents get lost; digital records with cloud backup don't.
From an efficiency perspective, spending a small amount on a service like Postclic can save you hours of time and potential stress. It's the same principle as using an accountant for tax returns—yes, you could do it yourself, but professional handling often prevents costly mistakes.
Your cancellation process isn't complete when they confirm termination. Here's what to check in the following months:
Monitor your bank account for at least three months after cancellation. Automated billing systems sometimes generate charges even after accounts are closed. If any charges appear, you have your documentation to dispute them immediately.
Check your credit file after about six weeks. Ensure that Smarty has reported the account as closed and that no negative marks have appeared due to processing errors. You can do this free through services like ClearScore or Experian's free tier.
Keep all your cancellation documentation for at least 12 months. Storage is cheap, and these documents could save you significant money and stress if disputes arise later. Create a dedicated folder—digital or physical—for all your cancellation correspondence.
Finally, if you receive any correspondence from Smarty after your cancellation date—bills, promotional offers, account statements—respond immediately to confirm your account is closed. Don't ignore these communications assuming they're just system-generated errors. Sometimes they indicate your cancellation wasn't properly processed.
