ZYM Mobile is a Singapore MVNO powered by the Singtel network, giving its customers 4G and 5G connectivity on the island's most established infrastructure at challenger prices. ZYM sells no-contract, SIM-only postpaid plans — you pay monthly by Visa or Mastercard, and there are no prepaid top-up cards to juggle.

ZYM's signature is roaming: its "Roam" plan family (Roam SAVER, Roam PLUS, Roam SMART and more) bundles yearly roaming data for APAC destinations, with especially generous allowances for Malaysia, Indonesia and Thailand — handy for frequent causeway commuters and regional travellers. Plans are managed through the ZYM Mobile app, with customer support a WhatsApp message away.

Why choose ZYM Mobile?

ZYM Mobile's pitch is simple: Singtel-network quality without Singtel-level prices, and roaming included rather than sold as an add-on. Its Roam plans bundle yearly APAC roaming data, so travellers to Malaysia, Indonesia, Thailand and beyond can often skip buying travel SIMs entirely.

All plans are no-contract, so you can switch anytime, and ZYM is moving with the national 5G transition — upgrading customers from 5G (NSA) to standalone 5G+ with a free 1-to-1 SIM exchange for existing 5G users. Add app-based plan management and WhatsApp support, and ZYM is a strong pick for value-focused users who travel in the region.

Frequently asked questions

ZYM Mobile is under which telco? Is ZYM under Singtel?+
ZYM Mobile runs on the Singtel network — ZYM itself states its service is "powered by the Singtel network." It is an independent brand (an MVNO), not Singtel itself, but your calls and data travel over Singtel's 4G and 5G infrastructure, so coverage matches what Singtel customers experience.
Does ZYM Mobile support eSIM?+
Yes — ZYM has announced that eSIM is now available. Check the ZYM Mobile website for the current list of supported plans and compatible devices. If eSIM is a must-have, you can also compare all eSIM plans in Singapore.
How do I top up my ZYM Mobile plan?+
You don't need to — ZYM plans are postpaid with no contract, not prepaid. Your subscription is charged automatically each month to a Visa or Mastercard, and you manage your plan, add-ons and payment details in the ZYM Mobile app. If you'd rather have a classic top-up-style SIM, compare prepaid plans here.
Does ZYM have a senior plan?+
ZYM has promoted senior-focused offers in the past, so it's worth checking zym.sg for what's currently running. Its regular no-contract plans are also simple enough to suit older users. To see every senior-eligible deal side by side, compare senior citizen mobile plans.
Does ZYM Mobile have 5G?+
Yes — ZYM offers 5G plans on the Singtel network, and it is upgrading from 5G (NSA) to standalone 5G+ (SA) in line with Singapore's national 5G transition. Existing 5G subscribers get a free 1-to-1 SIM exchange to access the upgraded network. Compare ZYM against other 5G plans in Singapore.
What is the ZYM Roam SMART 5G plan?+
Roam SMART is one of ZYM's roaming-focused 5G plans. It bundles free yearly APAC roaming data across 13 destinations plus a large yearly roaming allowance for Malaysia, Indonesia and Thailand, on top of its local data, calls and SMS. Live pricing and full allowances are shown on the plan cards above.
Is ZYM Mobile good?+
ZYM is a solid choice if you want Singtel-network coverage without a contract, especially if you travel in the region — its bundled yearly roaming is among the most generous of any Singapore MVNO. Plans are managed in-app and support runs over WhatsApp. The trade-off versus the big telcos is fewer physical stores and no handset bundles; compare it against the cheapest mobile plans to judge the value.
