Frequently Asked Questions
How do I know if my phone is unlocked?
Try inserting a SIM card from a different carrier. If you can make calls, your phone is unlocked. You can also check in your phone's settings or contact your current carrier to confirm.
Will I lose my data when I switch?
No! Switching carriers doesn't affect your photos, apps, or data. Your phone's contents remain exactly as they are — you're just connecting to a new network.
Can I keep my current phone number?
Absolutely! We'll port your existing number during activation. The process typically takes 1-2 business days and we'll handle everything for you.
What if my phone isn't compatible?
We offer a selection of new and certified pre-owned devices at great prices. You can also purchase a phone elsewhere and bring it to TheArena.
Do you support eSIM?
Yes! If your device supports eSIM (iPhone XS and newer, Pixel 4 and newer, etc.), you can activate instantly without waiting for a physical SIM card.
