How to repair cellular antenne of Lumia 820?
since a few days my Nokia Lumia 820 cannot connect to the cellular network any more. WiFi however works fine; the SIM card works with other phones, too.
When the problem started, the outage was just temporary and I could connect to the cellular network the other day. Now it’s completely gone…
I guess that the cellular antenna is not working. But I can’t find any information on it. So my questions are
- How can I doublecheck, if the cellular antenna is (not) working? (and thus is the cause of my problems)
- Where is the antenna located? Can it be replaced?
- Any other guess, what be the problem’s cause can be?
(Btw: ifixit seems to know only Lumia 822 devices - are these different phones or is it just a typo?)
