MetroPCS - SIM Card Information

To install your SIM card, insert the SIM card into your phone, using the correct adapter (if required). For devices requiring a standard SIM, use the larger included adapter. For devices requiring a micro SIM, use the smaller included adapter. Devices requiring a nano SIM will not require an adapter, but the adapters should be retained for future use in another device. If you are unsure which SIM or adapter fits your phone, please see a MetroPCS store or Authorized Dealer before attempting to install the SIM or adapter. Once the SIM is installed, insert your phone's battery and charge your phone.
