Troubleshooting The Sim Card

In some instances, removing the SIM and placing back into the phone may resolve this. 

1. Turn off the device
2. Remove the SIM card (you may need to use the tool that came with the phone to remove it)
3. Clean it with a soft cloth or blow away any dust around the card or inside the card slot.
4. Place the SIM back into the phone.
5. Power it on and test.

In some instances, the SIM will need to be replaced if it is damaged. To do this, chat with our teams to order a replacement.

I can make calls but the other party cannot hear me

[ShonDud]

I'm not receiving messages on time. I receive messages several hours late to whole day-three days late. Even when using 4G network with 3-4 bars and using WiFi calling sometimes and still receive messages late. My Friends/Family sometime ask why I didn't text back? I text back all the time and they don't receive my messages. Which it shows on my phone that it had been sent because the loading circle thingy don't show once it sent. I'm in a relationship and this isn't good at all. People try to reach me and I don't receive they message.. Oh! Yeah. And I don't receive their phone calls either (Sigh). Last night my partner called said he called several times and I didn't receive not one. Even my other friends told me that Three weeks ago. And when I called them my phone calls drops even when I have 4G with a few bars or all bars.... This is sickening I'm not a very happy customer anymore. I have a Galaxy S5 and had since December 2015 and its 2017 first time having this problem ever. Is it possible my phone need Re-provisioning. Or What?! Help Please

Hello,

I am unable to send or receive MMS.  I have had my Galaxy Mega 2 for about 5  years and  I have never had a problem.  Could you please advise me on what to do or maybe walk me though the process of being able to receive or send my photos.  

Thank You,

Liz Bateman

I have a galaxy note 2 and i loose service all the time in addition to dropping calls what do i do 

[AintNoSucker]

Me too! Regardless throughout 3 phones, new SIM cards & even phone number - would help for a few days here n there then back to no service for most of the months this year & regardless of signal... Which I've yet to be compensated for while paying $50 a month to get the "#AT&T Unlimited No Service Plan"...

AT&T has not fixed this issue. 

My wife and I just purchased net Galaxy S9 phones and switched our service to Consumer Cellular from Sprint. Big mistake!

Or cell service has been non existent sine day one.

The fist day a month ago customer service told us to go to Target and get AT&T sim cards for the phones. We did, made no difference in our signal. So last week I went to Ebay and purchased an Cell Phone Signal Booster. I installed the booster today.  Using the LTE Discovery app. I found my signal went from 102dbm to 65 to 70 dbm full bars. However, when we try to make a call the signal drops out to no service. We can not make or receive calls from inside our home.

Now customer service is sending us new sim cards again. This time we are going back to T-mobile sims. I have saw people say that calls are not made over the LTE signal. Having said that I am getting no GSM signal.

My ex husband has had service for years where he lives for years an years . Been going to store for 3 weeks now . First they put new sims card on his old phone then he ended up paying 1200$ for a new iPhone and it still with no service at his home . It stops service the home beside him and his home . If he can’t get service now what was the use of him having to buy a new phone like the store told him . They probably didn’t look on the tower map for his service but why has it stop picking up in all these years and now no service . He needs answers bc like I said 3 weeks an new high dollar phone that u can’t use .he has health problems an can not depend on att . So I need someone to contact me an give him some answers . Fast answers bc if he can’t call out an something happens with him then what . Need to make this good on his part . Contact me plez . Thanks
