FAQ: Public Mobile SIM card

Do I need a SIM card to activate Public Mobile?

If you’re using a phone without eSIM, yes. If your phone supports eSIM, you may be able to activate without a physical SIM.

Where do I enter the Public Mobile promo code / coupon?

During activation, enter ZPO82O in the referral code field (many people call it a promo code or coupon).

What SIM size do I need?

Most newer phones use a nano SIM. Many SIM packs include multiple sizes.

Can I keep my number when switching?

Usually yes via number transfer (porting). Keep your old service active until the transfer completes.

Why does my phone say “No SIM”?

Reseat the SIM, restart the phone, and confirm the device is unlocked. If possible, test in another device to isolate the issue.
