    I have the N20U locked to ATT and three of my friends who were able to send texts 1 week ago are now not able to send them to me, although I can send them out to them. I called ATT and they said everything is fine on my end. Does anyone know what I can do? Is it a cache or carrier settings issue on the phone or just a Verizon issue, which is weird.

    If you search these forums and find the threads that discuss SMS/MMS issues, most of them are phones that are locked to At&t. But At&t gives the same answer every time someone calls, it's not on their end. My wife and I had so many issues with our S20U's that we gave up & we both got N20U's. Now, I haven't had any issues, but my wife said last night that she had issues sending pictures or group messages.

    I had an iPhone, about 4 weeks ago. This is a recent issue. I've been getting texts until the last week from these same people. Not an imessage issue.

    There's a minor possibilty that your number is still in the imessage database. If you enter your number at the bottom of this link you'll know for sure.

    It's not an iMessage issue. I've never owned an iPhone and I have had the same problems before. It is clearly an At&t issue. In the past while being connected to LTE, I would have to force HSPA+ just so MMS would come through.

    That may be the case but you can't say for certain what the issue is just because you had a similar issue. When we try to help people here we go through a variety of steps to troubleshoot potential issues. Sometimes the advice we offer works and sometimes it doesn't.

    OP should try all suggestions because hell, I know I did. I hope something works for him. But I'm not commenting because I had a similar issue, I'm commenting because it's a known issue with dozens of threads not just here, but on Reddit as well. Android Police even did an article about customers complaining about having issues sending/receiving MMS on At&t's network a few months ago. I'm just letting OP know he's not alone and that his phone is not the problem and it's not a iPhone/iMessage issue.

    As I indicated previously, you may be correct, but we don't know until we try and eliminate the obvious. What did you do to resolve the issue if it's resolved?

    There's nothing to do...you can't do anything about a network issue. I did however change my APN to the NXTGEN APN which has been discussed on here before. I seem to have a little bit better signal strength, but I changed the APN on my wife's phone as well and she said she had MMS issues the other day. It seems to have been isolated to just that day, but still, as much as we pay for our phones & as much as we pay for plans, we shouldn't have repeated network issues.

    I also want to say that I commend you for trying to help your fellow man out. I'm not posting because I think you're wrong and OP shouldn't try your suggestions...I think he should.

    I'm going to the ATT store after work to see what can be done. I've tried what you all suggested with no luck. I hate that I went to ATT just to get the free N20 (with bill credits) now.

    He said he went to Att to get the credits, so it sounds like he's a new customer. Either way, I hope OP gets it straightened out.

    Try this... Go to settings>connections >mobile networks>APN. Top of the page you can edit or add APN's. Add this APN. Type it in exactly how you see it here Restart phone after, and give it a try. I get better signal strength with this APN, maybe it can help you.

    It should be configured correctly if done by store

    Correct, I was just saying it shouldn't be an old card if he's a new customer.

    Correct again. But it's been documented by other users, including me that they have had better success with the NXTGEN APN as opposed to the Enhancephone APN. He loses no features, and if he's willing to try it, go for it.
