My mobile data connection drops from 4g to dial-up-equiviallent speeds whenever I am on a call. I was wondering what may be causing this issue, and wether it can be remedied. I use my mobile data for work, so I need to have both working similtaniously.
Thankyou in advance,
Are you using a phone? What brand? What Age?
Basic 4G can't make calls, so some phones need to drop down to 3G to make the call.
Check your phone supports Voice Over LTE (VoLTE)
