How do I transfer my contacts from one SIM to another?
- Visit us in store and we can copy your contacts over for you.
- Depending on the software available on both phones and their compatibility, you may be able to save your contacts to your computer, then retrieve them using the software on your new phone.
- Again, depending on both phone's software, you may also be able to move your contacts via Bluetooth.
- In our stores that have Geek Squad services, we can use a SIM cutter to trim your standard SIM to a smaller one. We don't recommend using a SIM cutter yourself. The contact areas (the gold area) on different SIMs can vary in size, so it needs a trained hand to do the job correctly!
What are SIM adapters?
- SIM adapters are small, plastic holders which a SIM can be inserted into, increasing its size and allowing it to slot into different SIM spaces. Here are some of the SIM adapters available.
- If you purchase a mobile on the Talkmobile network, the SIM pack will include a micro SIM and reusable adapter.
