Roaming with my S3 on Jellybean??HELP??

I frequently run from Toronto to Buffalo. I took my S3 from ICS to Jellybean 4.1.1 and have had no issues until yesterday.
Upon crossing, I lost all service. I tried to go into the menus and see what was the matter without success. Later, I
realized that under MOBILE NETWORKS, Data Roaming wasn't checked. So I checked it off........still no service until
I was about a mile from the border, back on Rogers.
Anyone experience this?? I've bad numerous blackeberry's and cross without an issue all over the US and Caribbean.
I'm confussed.......and concerned about making another trip to the US, without my briefcase which has a backup blackberry
in it........
Suggestions? I fugured that checking the roaming box would have grabbed a carrier..........NOPE.........meanwhile,
my friend who has the same phone still on ICS worked fine................that's the strange part...........
Thanks guys.

Hi!
One thing you could check is if you activated the automatic selection of carrier, and if your phone can see other carriers' networks.
1. Go to Settings.
2. Under Wireless and networks, open More settings.
3. Under Networks, select Mobile networks.
4. Select Network operators.
5. Your phone should now disconnect and search for visible networks. (It should show networks you can connect to and ones you cannot; that is normal.) See if you find any carrier listed on this screen when the search is completed. If no network appear, press again Search networks to scan the visible networks again.
6. Press Select automatically to automatically register to the prefered network. When Rogers is in this list, your phone should register automatically to Rogers. If not, then it should roam on a network with which Rogers has a roaming agreement. You should also be able to manually select to which network you would like to roam by pressing the carrier's name (again, you will register only if Rogers has a roaming agreement with the said carrier).

Happened again this morning. However, I did what you said (here in Toronto) and it found BELL, TElus and Rogers. Now, it
would't find anything across in Buffalo. VERY strange. Called Rogers when I crossed and they were no help.
Could it be possible that it's an issue with Jellybean?? The phone is rooted and I used the Robinson's root injected JB ROM.
Suggestions? I'm crossing again in the morning... Can test more settings.....can't bring my old blackberry because it's a
regular sim and this thing uses a micro...

[Q] New phone -- no data. Suggestions?

OK, I took the plunge and got one. Checked a few things out, then went for the ICS update (official AT&T, at least for now) before I got too wrapped up in it. Seems I may have forgotten to check out that the data plan worked before the update -- I think I may have had Wi-Fi on all the time. Yeah, it was a dumb mistake.
Now I cannot get any data with any application when outside a Wi-Fi zone. Not even 2G, much less 3G. No connection and no indicator at the top. Phone is working on 3G just fine.
I have AT&T, though it's an old "Smartphone Unlimited" plan. It works just fine on my LG Expo (which is 3G). The phone is supposed to be unlocked (at least until I updated it, don't know if that affected it), but I have no non-AT&T SIM with which to try it. Have made no attempt to root it or load a custom ROM.
Are there some settings somewhere that I have to change to go through my old "wap.cingular" gateway (either rooted or not)? Should I try going to a custom ROM? Back to the original software (link, please, if that's the case)?
I'm going to see if a co-worker's T-Mobile SIM works with it (voice and/or data). But is there anything else I should try? Has AT&T finally caught up with me and my old, cheap, unlimited data plan and my SIM keeps me from connecting?

There should be no issue putting in a SIM from a working phone. If you go to System Settings->About Phone->Status, what is the network status? "Unavailable"? "Unprovisioned"?
Do you have signal, just no data, or do you have no signal?

I have full phone and text service, just no data (though, oddly, it says I have used 9.92KB of data). That occurs both at my home where I connect to my microcell and elsewhere. Of course, at home, I can also use WiFi for data.
"Mobile Network State" is "Disconnected". "Mobile Network Type" is "UTMS:3." If I turn the data network off and back on, it goes to "connecting" for a while, then back to "disconnected. I did find the location where it specifies the Access Point Names and it is set to "wap.cingular" just like my old phone. But unlike my old phone, the user name and password are "not set". These are uneditable fields.
I also went to the place it allows me to select my network operator and it offered me three different "AT&T" options. Two of the three gave me a message that my SIM does not allow connection to that network. When I try to switch to one of them, I see the data indicator go through Edge, 3G, and 4G, then off.
Only other odd thing I've noted is that the serial number is all zeros. The IMEI is correct, though; and I think that's what matters.
I'm becoming more and more convinced this is a problem with my SIM and the data plan it's tied to. It is from an old EDGE-only Windows Mobile 5 "smart phone" when that meant a device without a touch screen or QWERTY keyboard and a "PDA" was something that had either of those. The "Smart Phone" data plan was half that for a "PDA" but more than for a plain phone, and that's what I'm still paying. I've been buying phones outside of the AT&T system to hang on to that inexpensive, unlimited plan; but I may have reached the end of the line with it. I definitely need to try a SIM from another 4G capable phone,. both AT&T and T-Mobile, to see where I stand.

In the Access Point Names make sure that the profile you were talking about is selected. Or from that screen if you hit the menu button it should give you the option of entering your own APN. If you've had data working on another phone I would suggest duplicating the APN settings from it and try making a new profile.
It could be the SIM/plan you're currently on but honestly this sounds exactly like what happens when your APN settings aren't configured correctly.

Turn the phone off, remove the SIM, boot it with no SIM. Go into Access Point Names and remove all the entries. Turn it off, put the SIM back in, turn it back on. If it doesn't autocreate an entry in Access Point Names, or the autocreated entry still doesn't work, take it to an AT&T store and ask them for help.

There was no way to select the plan. So I made a duplicate of it, which did have a select button, selected it, and it now works great. Thanks so much for your help.

That would have ben last resort. They would have wanted to "upgrade" my data plan to something that cost more and isn't unlimited.
Your solution might have also worked, but the first one offered led me to a solution, so I never tried yours. I'll keep it in mind, though.

*#4636#* into the dialer, scroll down and then select the correct network option for you service provider, hit home twice - should be done for you

What do you mean by correct network option? Set preffered network option? Select radio band?

ok again *#*#4636#*#
* choose phone info, scroll down choose the dropdown option its the little arrow on the right hand side only one to choose, you get a menu choose the option that is correct for your sim provider
for example choose:
CDMA/EvDo/GSM/WCDMA/LTE auto
that should choose the best option for your phone
You can try any of the options as they change "live"

Yep. Tried different stuff and still get 3g or 1x on the same area I get 4g before.

Have you had data on that phone before? The nTelos network is not that impressive, especially for LTE. (Fortunately, that will be changing over the next year or two, as Shentel has bought nTelos, and the network will DEFINITELY improve!)

I've had lte on my home and workplace before. Any other far place would just suck big time. I'm pretty much going crazy as there are no resources for nTelos htc one m9. And I'm slowly losing my patience waiting for the latest software update.

How do you set a custom APN?

I just got a brand new unlocked HTC 10 today straight from HTC.com. My cellular carrier is Red Pocket Mobile - an AT&T MVNO.
I connected the phone to WiFi and applied the system update for Nougat. I'm trying to set my APN for Red Pocket and it's forcing me to pick a carrier from a list that doesn't include Red Pocket. I select AT&T to get passed this and it allows me to add my APN settings. It won't let me actually switch to that APN though. There's a lock icon next to the AT&T settings and it doesn't seem to want me to change.
I've never seen this behavior on an Android phone before. Is this something new for Nougat? Is there something simple I'm missing here?
Thank you for any assistance
PS: See the attached screenshot. Notice that there's no radio button for me to click on next to the APN I've entered.

The answer is you have to select "US Travel SIM" from the list of carriers for it to allow you to switch APNs. Of course I figure it out minutes after asking for help.. :silly:
In my defense, it's not real obvious.
EDIT: I am so confused. I selected US Travel and input all the APN data. It doesn't allow me to select it now. It allows me to when I don't fill it out entirely though.
EDIT 2: The instructions I have from Red Pocket instruct me to set APN Type to: Default,mms,supl It seems like putting this in disallows me from using the APN for some reason. I hope it'll work without this setting.

Question How to change preferred network type?

I'm on EE UK but the preferred network type setting doesn't appear to be present in SIM options?

It appears that some providers suck hard and don't want to allow you to switch networks. That's not a phone thing-y, it's a provider thing-y. Which means that your phone will of course still change networks, but only if the "higher" one is not available, ergo your phone will only connect to 4G, if 5G is not available - if the 5G connection is bad, that will probably cause problems for you, because your phone will probably not want to connect to 4G automatically.
I can easily switch preferred network types
Settings -> Network & Speed -> SIMs -> (scroll down, between 4G Calling & Carrier settings version) -> Preferred network type (5G, 4G, 3G, 2G).
It that's not available, your network carrier sucks. No more to say here.
I'd suggest you either switch providers, or contact your provider to see if they are willing to change this. It's definitely on their end, cuz people like me can change the settings easily.

You may be able to change preferred network type with *#*#4636#*#* dialer code.

EE (& BT Mobile) hide the menu.

Or you could just make sure Adaptive Connectivity is enabled and not worry about it.
You would have to drag me away from EE (BT Mobile) screaming and kicking given the coverage and speeds they have, to say they suck over one menu option missing is absolutely laughable.

When the Note 20 first came out a lot of carriers wouldn't let you change network type but there's an app in the play store that was working on the notes.
Force 4G/5G Only - Apps on Google Play
Lock your phone to 4G/5G mode or VoLTE network

Crashes or alternately just disappeared for me when I click on the first option "4G LTE with only one SIM". Reported the crash. Thanks, though. Maybe they'll update it.

An alternative to the dialer code is to boot into safe mode, and the preferred network type setting will appear in: Settings -> Network & internet -> SIMs between Data warning & limit and Carrier settings version (at least it does on my Google Fi Pixel 6 Pro).
