A SIM is a tiny card with a big job. It stores your data and carries a unique identification number that links you to a specific mobile phone company.

Without a SIM card inside your phone, or if the SIM is not working correctly, your phone will not be able to make calls, send texts or connect to your mobile network.

Need a new SIM card?

Getting a new Koodo SIM card

SIM cards come in different sizes. Check your phone’s user guide to see what kind of SIM it can hold. If your current SIM does not fit the phone you have, you’ll need to replace your SIM. The LTE Koodo Tri SIM card offers Standard, Micro, and Nano sizes to give you the convenience of 3 sizes all in 1 convenient card. Simply push out the large white card, the medium multi-colored card, or the small white card, and insert it into your phone.
