What do I do if I see a No SIM error message after applying the KnowRoaming Sticker?

If you've applied the KnowRoaming sticker to your SIM card and receive a 'No SIM' error after inserting your SIM card back in your phone, please do the following:

1.) Power your phone off, then back on.
2.) If you still see a No SIM error, do not remove the sticker from you SIM card, please contact the 24/7 KnowRoaming Support Team: or 1-888-357-7347
