iPhone 11 128 GB White A2221 with Network Reception Issue

### NO EXCHANGES FOR OTHER ITEMS ### iPhone 11 128 GB / White Domestically purchased, used iPhone, bought in 2020; always used with a case, screen protector, and camera lens protector. Description of the Issue: The phone is fully functional, but occasionally loses its 4G connection; when receiving calls, it may indicate that the device is powered off, though reconnecting resolves the issue. I believe there is an issue with network signal reception. The device remains in original condition—never repaired or opened. Battery capacity is at 80% (Photo 7). Included with the sale: - MagSafe case with rear support. - Charging cable (power adapter not included). Notes: - No exchanges for other items—I am only interested in selling. - I do not ship via courier services; transactions are strictly in-person only. - Payment accepted via MB WAY or cash. - Delivery available within the Lisbon area (Amoreiras, Marquês de Pombal, Saldanha, Entrecampos, Campo Grande, Alvalade, Roma). Thank you!
