My phone was unlocked from Bell and won't go online. If it does, won't stay online. Some functions work, like hot spot to my other phone. My battery only lasts about an hour?
Yeah, should be able to work in 3G network. Make sure phone is not carrier locked before moving to another carrier.
Hmm.. seems that you're having problems with the phone. Back up your files and try restoring to factory settings. Observe if problem persists.
