Upgrade to eSIM

Maybe you just upgraded your phone to an eSIM capable phone, or you just don't want to fiddle with a tiny physical SIM card and your current device already supports eSIM technology?

You’ve come to the right place! OneSimCard has you covered because we offer some great options if you want to upgrade to a new eSIM.

First, what is "eSIM"? eSIM stands for Embedded SIM card. This is a virtual SIM card which replaces the need for a physical plastic SIM. Most newer devices support this technology and installation is simple and fast. The eSIM is delivered as a software download by scanning a QR code.

There are some great advantages to moving to eSIMs over physical SIMs:

• This is only software, so there is nothing to ship, just scan and go!
• Because it is "embedded" into your device, there is no risk of losing that tiny chip.
• Switching between SIM cards is much easier since you don’t need to pop out the SIM tray and fumble with SIM cards.
• You get the same great service you are used to with your OneSimCard, and the DataMax eSIM offers HUGE savings on data.
