The HTC Thunderbolt has just got out of Verizon’s front door, but we are already hearing about some problems on the device, with users complaining that there is an SMS bug preventing them from sending messages effectively – does this apply to you?

This hasn’t been confirmed by Verizon yet, but it is bound to be a fresh headache for the carrier who came under criticism for their repeated delays of Verizon’s first 4G LTE capable smartphone.

The apparent problem is an unusual one as welll, as we’re hearing that when some Thunderbolt users send messages, the recipient sees a SIM card number on the calling display, rather than their actual number. This has been clarified on both the XDA Forums, and Android Forums, as reported from Phandroid.

Aside from the fact that some users are having problems sending any messages at all, we’re hearing that some recipients are getting double messages as well. We don’t know how widespread this problem is at the moment, so help us out and tell us if you are experiencing any problems on your Thunderbolt.

We’ll update this as soon as we hear from Verizon.
