Cancellation service #1 in Singapore
Zym is a mobile service provider in Singapore offering postpaid mobile plans, roaming features and call/data services on a Singtel network wholesale arrangement.
Plans are generally non‑contract (no fixed long term) and offered as physical SIMs with plan features such as large local data buckets, roaming allowances and short promotional 5G access for new sign‑ups.
Key offerings include multiple “Roam” plan tiers, a data‑only option, and roaming allowances for nearby countries.
Billing is monthly and the first bill includes a prorated first month plus the next month in advance; delivery and deposit terms may apply.
Termination usually takes effect at the end of the billing month. You will generally keep access until that effective date.
Subscription once terminated cannot be reinstated under the same subscription - you would need to sign up again as a new customer.
No prorated refunds are issued for unused days; you may be billed for the full month even if you port out early or your port overlaps months.
If you cancel within the first two months (the minimum subscription period), a cancellation fee equal to the two‑month minimum applies.
Below are ZYM plan names, prices and core features. Prices quoted are in Singapore Dollars and accurate as of 27 February 2025.
All plans listed are postpaid and non‑contract unless stated otherwise. Physical SIM only; eSIM is noted as coming later.

Under Singapore law consumers have protections for fairness and disclosure; service terms that are clearly disclosed are generally enforceable.
ZYM’s terms state no refunds, no prorating and mandatory notice periods; these terms may be enforceable if they are fair and were clearly communicated at sale.
Many users praise ZYM for using the Singtel network and for good roaming coverage and value for money.
Reports include strong 5G coverage in many areas and generous roaming allowances during promotional periods.
Frequent negative feedback covers poor customer service, delayed SIM delivery and slow responses when problems occur.
Some users reported network issues in certain underground MRT stations and problems with iMessage/FaceTime verification after porting in.
Example: starting termination 2 days before a billing date can lead to the next month being charged because many channels require 14 calendar days or at least 3 days notice.
Always check your next scheduled recurring payment date and start the process early.
Example: attempting to cancel an App Store/Google Play subscription through ZYM support instead of via your Apple/Google account can leave the subscription active.
For store/website signups follow ZYM’s termination steps; for app store subscriptions turn off auto‑renew in the account used to subscribe.
| Feature | What ZYM requires / offers | Key note |
|---|---|---|
| Notice period (website/retail) | Initiate termination or port‑out ≥14 calendar days (by 5 pm) before next recurring payment | Failing this may incur next cycle charge with no refund |
| Shorter notice statements | Termination requests should be submitted ≥3 days before next billing date; termination takes effect end of month | Different channels have slightly different cutoffs - confirm via CusCare |
| App Store / Google Play | Auto‑renewal must be turned off ≥24 hours before period end via your account | Cancel through Apple/Google, not in‑app |
| Refunds / Prorating | No refunds or prorated credits for unused days or early port‑out | Deposits refundable after final settlement (next month) less outstanding charges |
| Minimum subscription cancellation fee | Cancelling within first two months triggers two‑month minimum charge | Check terms at sign‑up for any minimum period language |
| Effective date | Termination usually takes effect at the end of the billing month | Expect service until effective date unless otherwise notified |
