Roaming Issue

Gerry_P — Sun, 27 Feb 2022 19:14:17 GMT

Currently in Florida and connected to T-Mobile with a strong 4G signal. I have the Talk/Text/Data ad on. The issue is that at times my phone (Android 10) will disconnect then reconnect to the cellular network every 10 seconds. I'm also getting a random message that the sim card memory is full but as far as I can see there are no text messages or contacts stored on the sim card. Has anyone else experienced an issue like this? If I clear storage on Message and Carrier Services apps and restart phone it will work properly for a few hours but inevitably starts acting up again.

@Gerry_P are you getting many carrier SMS messages about you are now joined to the TMobile and using roaming , etc?

Did you manually select T-Mobile or using Automatic connect? Please manually select T-Mobile and not rely on Automatic. Sounds like the Automatic keep searching and reconnect network

I only received the text from Public Mobile once when I entered the US. I'm pretty sure the issue is just with my phone or sim card because my wife has and Android and hers is working fine.

Hi @Anonymous hope there is confirmation from user about VoLTE

Hi @Gerry_P if you have time, can you try joining AT&T and enable VoLTE and try to make a phone call to see if VoLTE works there? thanks

I've tried but the AT&T network doesn't even show up in my network settings. Is Volte 5G? I don't think my Umidigi Bison has it?

@Gerry_P

Maybe try the following:

Network reset of phone.

Remove SIM card and re-insert.

Manually select LTE or 3G. See whether that makes a difference.

Hi @Gerry_P VoLTE is 4G/LTE. If your phone has 5G, you can try to connect to AT&T 5G, you can then try to set your network to 5G or 4G only to first test if Mobile Data works. If it works, then try enable VoLTE and see if voice work.

This is a great exercise in troubleshooting! If your wife is PM customer and has same or similar US add-on and her phone works perfectly - then you have an answer 😁. Something might be off with your phone. Maybe contacts with SIM are loose; try to re-seat SIM, gently wipe contacts, blow out potential dirt/dust from the phone.

Check her phone's settings; compare with your phone's. Adjust if needed.

Yes, my wife's phone is on PM with the same add on. The same phone as I have except android 9 and mine is running 10.

Network settings appear to be the same and yes, I pulled and reinserted my sim card a couple of times too. It's a very wierd issue.

My phone is not 5G compatible,the only options in network settings are 2G, 3G, 4G

@Gerry_P : The question and test is more about testing out something. Not to fix your issue. We would be interested in your findings on this but I don't know how techy you are.

Somewhere in your phone settings might be an option to use VoLTE if available. But it also might be greyed out (like mine).

Edit: I hope an Oracle can pull this conversation out of this thread that was started by someone else and move it over to this customers thread called Roaming issue.

@Gerry_P

Have you switched sim cards with your wife? This will determine if it's a device or a sim card issue.

@Gerry_P

I'm curious, are you guys able to connect to "volte" for phone calls? try connecting to at&t. I think they have started shutting down 3g towers. I'm wondering if pm customers are able to connect to "volte" for voice calls

Re: U.S. Roaming after 3G/HSPA network shutdown in the US

Gerry_P — Sun, 27 Feb 2022 20:25:48 GMT

I have an Umidigi Bison with Android 10, Volte doesn't appear to be an option at all.

@gpixel

Switching to at&t will result in no voice services. Pm has not enabled voLTE calling for any pm customers including those using US roaming add ons.

@Gerry_P

Your phone seems to be enabled for VoLTE. It's just called "4G Calling" on your phone. But it's the same thing.

What we are all interested to know is if you make a phone call (while connected to the AT&T network), does the indicator at the top of you screen change from 4G to 3G?

I know when I was in Palm Springs last Dec., whenever I made a call, it would always drop down to 3G during the call, and then back to 4G after I hung up. It would be interesting to confirm that Oracle's comment that VoLTE was available in the USA now while roaming. If true, then your phone should stay on 4G during the call.

Enquiring minds want to know 🙂

That was great from @whyveeare . So you have 4G Calling set on. You have 4G recommended set. I see T-Mobile under automatic. Can you tap automatic and let it search for carriers and hopefully find AT&T and if so select it. Then try to make a call and look for evidence. I don't think it will. But we'll see. You should be able to do text and data with AT&T. But we're wanting to see what happens with talk.

Gerry_P — Sun, 27 Feb 2022 21:51:11 GMT

Yes exactly, I was planning on trying that in my troubleshooting plan. I need to find a paper clip to pop the sim drawer. I'll check with the hotel desk clerk 🙂

Thanks for all the great suggestions 🙏

The PM community is amazing!

@Gerry_P -

What are the models of your phones?

Can you check to see how much storage space is listed Used vs. Unused on each of your devices?

It is odd that the message only started when you entered the US.

I wonder if the android 10 is taking up more space on your device than your wife's android 9 version? Was this a recent update you did?
