Some phones have different-sized SIM card trays, so you may have to use the SIM card sizer tool that came with your TextNow SIM.
There are three SIM card sizes that you'll receive:
- Nano (smallest)
- Micro
- Standard (largest)
Open your phone's SIM tray and find the SIM size that fits your device:
- For nano SIMs (the most common SIM size for newer phones) you'll need to pop out the smallest piece to use on its own.
- For micro SIMs you'll need to make sure the nano SIM is inserted into the middle piece.
- For standard SIMs you'll need to use all three pieces fit together.
