Unlike other providers, Teal does not build regular SIMs, Teal only builds eSIMs or eUICCs. But eUICCs can still fit into a traditional SIM slot by picking the 2FF/3FF/4FF form factor instead of the embedded MFF2 format.


Most devices manufactured in the last 5-10 years support eSIM. There is wide support from the main module manufacturers, including uBlox, Quectel, Telit, SIMCom, Sierra Wireless, Gemalto, Nordic, Particle, and Pycom. If you have a recent module from any of those providers, your device will work just fine with Teal eSIM.
