Chosen Solution
- Phone suddenly starts to overheat.
- 1 SIM card stops working in it (works in another phone)
- Other SIM card works/detected but says: “DIALLING” until it “timed out” or eventually goes through.
- Battery then goes bad and swells.
- Same problem even when battery replaced, it just drain the battery to nothing - literally!

Thank you very much! Just needed a confirmation. I tried other means for powering the phone and realized that it really needed new battery. The other SIMM also worked when added.
