SIM card connection lost
#1
Hi there,

I am new to the Pine, which works surprisingly well out of the box (Manjaro Plasma).. however, there is an extremely nasty bug, and I am not sure whether its a damaged hardware or rather known problem: my SIM card disconnects every few minutes and the only solution is shutting down, taking it out, back in and rebooting again. Since I tried it with several SIM chips, if a new one, I am sure it's not on their end. Any work arounds available? Experiences/solutions to be shared?

Thanks!

I had a similar issue and "fixed" it by making a shim out of a small piece of flexible plastic cut from a milk bottle and inserted between the SIM card and the metal frame of the holder. Works great, have not had a problem with the SIM not being detected since doing that. (The problem may have to do with variations in SIM thickness. I never had that issue with the Tracfone SIM I used initially for test purposes, it started with my AT&T SIM.)

I tried taking a photo, it's not very good but you can just about make out the translucent plastic shim in this photo.

Jay Jay, are you using a nanoSIM adapter or do you have a microSIM? If a nano, be very careful taking the SIM out. Many have reported breading the delicate SIM contacts. One broke off on my phone and I managed to solder it back on. All the adapter I have have sharp edges and are prone to break the contacts, especially if the SIM card falls out of the microSIM adapter frame.

Thanks Zebulon, will try your "solution", interesting indeed!

Thanks, Isitongia, I am using a microSIM. So far, no issues when taking the card out/in, but your word of warning is certainly relevant. I avoid taking it out completely, just moving it a bit would do the job and after rebooting it connects again.
