I855 text messaging

Got a boost mobile n can't send text from my i855, it says "number not in service". please help.

If you just activated the phone through boost mobile you might have to wait an hour or so, then it should work, if you have a nextel phone you need to work on Nextel you can visit here to configure it.

even though i know the i855e is for Boost Mobile

If this your motorola i855e is a Nextel phone, then not all the features will work very well if you put in a Boost Mobile sim card. Features like Texting, Web browsing are not likely to function very well or at all. Get a Boost phone for a Boost sim card. Cheers.
