HTC one A9s won't connect to 4G unless I force it but then can´t make calls

[Android Central Question]

Hi,

My HTC one A9s only connects to H+ unless I restart the device which is very unconvinient or force 4g only using *#*#4636#*#*, if I do the latter I cant make calls or receive them as 4g only is activiated and my provider doesn't do calls over 4g.
This happens wherever I go and no matter how strong the singal is. It is very annoying.
Regards

Daniel.

Have you gone into the orivider's store and asked what to do about it?
