The physical SIM cards offered by GTN are all provided in a multi-cut form, which means they are compatible with standard SIM, microSIM, and nanoSIM sizes. However, there may be cases where devices with SIM lock or network usage restrictions imposed by other carriers may not be compatible, and you may need to request unlocking from your point of purchase or carrier.
*It is possible to directly insert the SIM into your device and test it at stores operated directly by GTN in each country.
