Today, my wife’s iPhone 5s suddenly lost cellular signal and says no service. I tried the standard routine - rebooted, airplane mode on and off, reinserted SIM, switched SIM from different phone, reseted network settings - still the same issue. The phone shows ICCID, but can’t find any carrier. Interestingly it is able to connect to the network partially. Inside of the house, where my iPhone 6 gets full edge signal, my wife gets no service, however outside, where I get only two dots of LTE, she also gets two dots. So maybe her iPhone is able to connect to LTE but unable to connect to edge? Have anyone else ever encountered such issue? Are there any known fixes. Do you think it is worth trying to replace the cellular antenna flex? Thanks.
Just a followup. About a month after the problem first appeared it suddenly disappeared. Since it was clearly not caused by the hardware, and there was no update, the problem was probably the carrier. Thank you all for your help anyway :)
It sounds more like a carrier issue than a phone issue. Maybe your carrier issued new settings and you need to update them. These are different from your iOS version, try contacting your carrier.
HI, did you found the answer where is the problem ? or still is it like that ? might be something on motherboard ?
