It doesn't really matter what you use, however I used a cut up piece of foam (earplug) to apply pressure to the area with the ribbon. See the below photo and please note that it was taken with a webcam so the orientation is reversed to what it really looks like." The cheap soft foam earplugs work great because they apply even pressure to the right spot.Other Android Phones: Sony Xperia, LG Optimus, Motorola Droid, Huawei Ascend, ZTE, Dell, Acer, Asus, and more.Has anyone else had an issue with their Galaxy S4 constantly coming up as the sim card not being detected and having to reboot?When the new Sims card was acting up in the phone I realized the card wasn't the problem it was the phone.I called AT&T they said it was a system hardware problem and the sent a new s4 out and the old Sims card been working perfectly fine with the new phone.I take no credit for it and am only passing it along.
The pressure of the cover does the rest, as soon as I turned on my phone again I got my mobile service back. (((The Best solution ))) Just put & stretch out clear scotch tape on where the sim card goes.

2 things I did was 1: before cutting the phone back on regular I would hold the power button and the volume button until a blue message pops up in the left corner than I would clear partition cache and than reboot the system that would work for two days and than It would mess up again. I would cut the phone off , cut it back on , while the phone was cutting on I would non stop press on the home screen button until the phone goes in safe mode when the phone is on I would go to settings , home screen mode and click on easy mode than I would immediate restart the phone and that worked very well for weeks.
When my phone started acting up again I completely got a new Sims card.
Google doesn't seem to help besides sending it off for repair which I'm pretty close to doing. What did WORK was the following: -I folded a small piece of paper multiple times And placed it to the left of the flash on the back of the phone then put the cover on. I have not had the issue for 2 days now, compared to 5 times daily.
This is definitely a hardware issue Found the solution to this issue as I was having it also and it worked like a charm.
