I have an iPhone that is capable or reading the sim card, but the connectivity is just not all right. The majority of the time the sim card will be read and picked up, but the service bars are usually weak. The phone will work fine for a bit then drop service intermittently. I've looked at the pins inside the phone and they seem to be doing alright. I applied a little pressure to try to fix the connectivity, but after putting the phone back together the same problem persists. Can you replace just the sim card slot on the motherboard?? Do you even have to take this step? Anyone know any tricks regarding this issue. This phone is perfect except for this. Would love to get it going properly.
