On most phones, the SIM card can only be installed one way, with the logo side up and the cut-off corner of the sim card matching with the cut-off corner of the phone's SIM tray.

When you purchase a Tello SIM, 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 1 SIM card and that 1 SIM card contains the three different sized punch-out SIM options.
Follow these simple steps to install the SIM correctly but only AFTER you have activated the SIM from your online account.

1. Turn off your phone. If you already have an old SIM Card in your phone, remove it using a SIM card eject-tool or the tip of a paper clip.
2. 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.
3. Carefully punch the size that will fit your phone and insert the new SIM logo side up. Your Tello SIM is now installed.
4. Turn on the phone, follow any on-screen steps provided and your phone should start to automatically activate the Tello service.
5. If by chance your phone does not activate automatically, please wait 30 minutes, then reboot your phone and try again.
   You can also manually activate your phone by following the steps provided under the FAQ at the bottom of the My SIM page.
