Where can I buy a micro or nano SIM card?

Does your current SIM card not fit in your new handset?

You can easily buy a multi SIM card online or visit a BASE Shop. A multi-SIM card consists of three pieces: a standard SIM card, a micro SIM card and a nano SIM card. You simply push the smaller card out of the larger one.

Your current SIM card remains active until you have activated your new SIM card online.
