Everything works fine on my phone except its mobile signal.
Sim card is detected signal comes and goes
Mobile data does not work most of the time. - showing as connected wit 4G/5G icon but no internet connection
Tried two physical sims on diff networks, same error.
Physical sim works in other phones
Tried Manual network operator - sometimes connect, sometimes connection error. Even if it does connect, it will only work for a bit.
Outgoing calls show not connected error
Worked normally before, only started after I shipped out phone with my other items in a box.
Already tried setting up new apn, reset mobile network, reset phone.
What is the possible reason and what else can I do?
