I recently received my new 4G SIM in the post after upgrading to a 4G tariff, however my phone still displays H+ next to the mobile data indicator.
I have tried resetting network settings, APNs etc to no success. I know people have said wait for refresh date, but my brother upgraded at the same time and his said 4G as soon as he inserted the new SIM.
Using an unlocked HTC 10 if that helps. Any help would be appreciated.
