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 or purchase one online if it doesn't fit in your new device.
There are three SIM card sizes that you'll receive:
- Standard (largest)
- Nano (smallest)
Open your phone's SIM tray and find the SIM size that fits your device.
- For standard sized SIMs you'll need to use all three pieces fit together.
- For micro sized SIMs you'll need to make sure the nano SIM is inserted into the middle piece.
- For nano SIMs you'll need to pop out the smallest piece to use on its own.
