ZYM Mobile SIM-only plans are all no-contract monthly offerings, which have several free inclusions: number port-in, caller ID, incoming calls and incoming SMS. All plans (except for ZYM Mobile’s cheapest one) come with 100 outgoing local SMS. If you’re after a ZYM eSIM, you should look elsewhere, because this telco only offers physical SIM cards via delivery or in-person collection.

The cheapest SIM-only option is the ZYM Mobile Flexi Duo Data Only Plan, which costs $7 per month for 77GB of data, which can be used in Singapore or Malaysia. There aren’t any calls or SMS with this plan, but it does include 100GB of roaming data for Malaysia (90-day expiry). Compared to similarly geared plans in our database, this ZYM Mobile plan is the cheapest, though you can get more data from Zero1 and Maxx (plus calls and SMS) for not a lot more. Here’s a list of popular SIM-only plans from our database, capped at $10 with at least 77GB of data.
