When you purchase a Tello GSM SIM Card, you receive a 3-in-1 SIM card that includes mini (2FF), micro (3FF), and nano (4FF) sizes to fit any type of compatible phone. You receive a big card with 1 SIM card and your activation code. That 1 SIM card contains the three different sized punch-out SIM options.

Take a close look at your phone's SIM Card tray size and then note the three different sized cut-out SIM options we sent you.
Carefully punch the size that will fit your phone and insert the new SIM.

To insert the SIM, please follow the next steps:

On Most Smartphones

1. Into the small hole on one of the phone's edges. This hole can be located in the top, bottom, left or right edge depending on the band of your device, please make sure to check your respective device instructions.
2. Insert the SIM ejection tool ( or a similar tool , eg. paper clip)
3. Firmly but gently push until the tray pops out.
4. Remove the tray and put the SIM card in the tray.
5. Gently push the tray with the SIM back into its slot.
6. Turn ON your phone and test the service.

Flip Phones and other featured phones

1. Check your device manual to find the location of the SIM card tray. In most flip phones and basic phones this will be on the back of the phone and below the battery.

*Some models of smartphones might also have a removable battery and the SIM card tray could be located below or close to it.
2. If applicable, remove the back cover of your device, locate the SIM card tray (it will usually be indicated with a SIM card icon)
3. Insert the SIM card. This is normally done by sliding the SIM card into or under the tray.
