I have bought a HTC Desire 816 Dual Sim which shipped from Dubai but is set for Vietnam according to HTC. The phone on all parts works fine apart from I can't use the UK 4g network. I have used the code *#*#4636#*#* to look at phone info and the option is there for lte but still only getting 3G
I am looking to Root the phone and install a custom rom/stock UK rom but will this let me access the UK 4g network?
According to HTC and seller the phone can do the right bands in the uk but how or if I can is beyond me.
Thank you in advance to anyone who is willing to help
Dear D179, you did indeed mention in the first post that your phone is dual sim model. As a thumb rule, no dual sim mobiles are 4G capable so far. You could only get 3G or H+ speeds on the first sim and only 2G or G on the second sim. May be in the future dual sim mobiles could be 4G capable.
Also, rooting and unlocking does not help you at all to get the 4G capability as it should have a radio that should be 4G compatible in your mobile phone, but all dual sim mobiles are only 3G capable radios.
You might find a custom rom for the single sim version of HTC 816 desire mobile (EU or UAE models), and after installing you can see that your network is getting 4G speeds, but it is all not real. Just the icon will say 4G but indeed you get the 3G speed only. Most of all, the custom single sim rom does not work properly on the dual sim model.
