Verification SMS / Text Message doesn't arrive...

Here are a few steps that might help:

1) Are you trying to register an iPhone on T-Mobile? Though Loopt doesn't currently support iPhones on T-Mobile, some of our users have gotten Loopt to function. Check out what one of our users posted: http://davesource.com/Solutions/20090...

2) Make sure your phone is compatible with Loopt via the link below. Note that the phone model must be listed under your wireless company on this page to work. For example, not all the BlackBerry models listed on the page are supported on every wireless company. Make sure your specific model is listed under your wireless company. If it isn't, you won't be able to verify: http://www.loopt.com/phones

3) Did you recently move your number to T-Mobile or Verizon from another wireless company? If so, it usually takes 4-5 weeks for Loopt to be able to send messages to your number via your new wireless company. If you try to register again 4-5 weeks after switching to T-Mobile or Verizon, it should work. There isn't currently a way around this.

4) Are you trying to register a non-US mobile number? Loopt doesn't yet support non-US mobile numbers.

5) Try sending a text message with the word START to 29201 to reset messaging, then remove and reinstall Loopt and try registering again.

6) If you haven't tried registering from Loopt.com on your computer, try that:
https://app.loopt.com/loopt/sess/Sign...

7) If none of the above help, please email support@loopt.com with the mobile number, phone model, and date of birth you're trying to register, and we'll be happy to help.

Thanks,
