DROPPING CONNECTION

[bigfil]

I have a Samsung A71 mobile phone that I have had about a year now.

For the last couple of months I keep getting the message :No sim card" which then requires me to reboot several times a day.

What can I do to stop this continuing?

@bigfil: I'm sorry to hear that you're experiencing this issue. At what point do you encounter the error? To ensure that the problem isn't stemming from the SIM itself, I recommend reaching out to your network provider to request a SIM swap to see if this resolves the issue. Alternatively, power off the A71, remove the SIM and give the gold contacts a rub with a clean, dry cloth.

Just cleaning the sim seems to have done the trick. It's often the simplest things that work but get overlooked.
Thank you.
