*Important Note: IOS manufactured for the Chinese Market have 2 physical SIM card slots and are not eSIM capable. iPhones and Pixel phones can't use eSIM if the phone was purchased in Japan, or if bought with Verizon or Charter service. Check with your service provider and product manufacturer to ensure your device can operate with a 3rd party eSIM.

Here's how it works: The OneSimCard DataMax eSIM global SIM card can only be installed onto one eSIM capable, unlocked device. The software installation instructions are extremely simple, and it only takes 30 seconds to complete. Once the eSIM is installed, your phone becomes a dual SIM phone, and you will be able to select which data service to use and make changes to this selection at any time if required.

Data service is included with the DataMax eSIM eSIM. Additionally, if you chose to order a Personal Extra Number (PEN) with your eSIM, then you will also be able to make and receive low-cost calls and SMS messages using our OneSim VOIP app. US and Canada PENs allow to receive and send texts.
