MMS need data, so if you have weak 3g signal that will also be an issue
Instead of the stock messaging app...try using Google Hangout app...that will group your Group SMS into a single thread.
I spoke with AT&T, and they walked me through the APN settings. I'm thinking that it boils down to the coverage in my area.
I've already listed it on eBay.
Just out of curiosity, and because I'm fairly ignorant to signal bandwidths and such, do you think the LTE version of this phone will work with AT&T??? According to gsmarena.com, these are the bandwidth specs of the LTE model:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA
4G Network LTE
Thanks for your help.
I found these specs on the merimobiles website, but have no idea if they jive with AT&T: 4G TDD-LTE 38/39/40/41.
Any help would be appreciated. Thanks.
