M1 Maxx FAQs

M1 Maxx, as the name implies, is a sub-brand of M1. Maxx is exclusively focused on providing competitively priced SIM-only mobile plans in Singapore. The telco doesn’t offer any prepaid plans. There may only be a few SIM-only choices, but they’re all priced under $20 for 30-day, zero-contract plans.

Maxx doesn’t offer mobile phones to pair with plans, but all of Maxx’s SIM-only plans come with hundreds of gigabytes of data and international roaming data. At the time of writing, Maxx wasn’t offering 5G support for its plans, but the Maxx website says it’s coming soon. Until then, all Maxx plans operate on the M1 4G network.

Here’s a breakdown of the most popular M1 Maxx plans in our database.

M1 Maxx mobile plans

M1 Maxx only has three SIM-only plans, all of which have no contracts and operate on 30-day billing cycles. They all operate on the M1 4G network and have unlimited incoming calls as well as free caller number display, plus a $0 SIM card with free delivery. There’s no word on whether Maxx supports eSIM, though Maxx’s owner M1 does. Base plan data is shareable in Singapore and Malaysia across plans.
