What Is The OneSimCard DataMax International SIM Card?

The Physical 3-in-1 DataMax SIM card is our lowest-cost prepaid cell phone service for those traveling around the world. OneSimCard DataMax global SIM card is a small chip (triple cut for Mini/Micro/Nano form factors) which, when inserted into an unlocked mobile device, enables the phone with international mobile service.

The OneSimCard DataMax SIM card is designed specifically for international travelers who:

  1. Want inexpensive international cell phone service;
  2. Want our lowest cost data options with Voice and SMS capability powered by our simple-to-use, cost-effective OneSim VoIP app
  3. Already have an unlocked mobile device

Here's how it works: The OneSimCard DataMax global SIM card comes pre-programmed with access to low-cost data access in over 200 countries and territories. In addition to data access, you will be offered a free 30 day US or Canada number (PEN - Personal Extra Numbers) when you activate the SIM. This PEN is used with our OneSim VoIP app for calling and SMS services. You can keep your U.S., Canadian or other phone numbers by forwarding them to your PEN.

If you do not already own an unlocked device, you should consider purchasing an international cell phone bundle from OneSimCard.
