Q: GSM issues when traveling in New Zealand/internationally? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I tried to use my Sprint S4 while in New Zealand and found that I had to manually reconnect to the local Vodafone network several times a day. Most of the time I was denied a connection with a message saying that the SIM card was not permitted on the network.
Sprint triple checked that everything was OK on their end and kept saying the problem was with Vodafone, which may be entirely accurate. However I don't want to travel again and find out that there is a problem with my SIM card or the phone.
Any problems like this in NZ or otherwise internationally?
Any ideas on how to test the SIM card or other functionality?
I'll probably ask Sprint to replace the SIM card as a precaution.

Roaming problem

Since some months I'm in Egypt for business reasons. I don't use my hermes very often here, because I'm having some duty phones. More or less I'm playing around with it, every now and then I'm turning the radio on to look for text messages from good old Austria.
I'm using an Austrian ONE Sim card and roam with Vodafone Egypt. In the place where I'm leaving I have 100% net.
Some days ago - I was testing S2U2 - I noticed that I can not call my hermes while the Austrian Sim card is inserted. I tried it with two different duty phones with Egyptian Sim cards, I tried it with another phone with an Austrian Sim card in it, its always the same: "The number you've dialed is incomplete". Of course the number is not incomplete. I can make phone calls from my hermes with the Austrian Sim card in it, but I can not call it. BTW: I tried it with UMTS on and off, same result. Its working fine if I insert an Egyptian Sim card, so apparently its a roaming problem.
Its not that important, because I don't use roaming with my hermes (too expensive, thank you very much ONE *ggg*), but I'm curious whats going on. Guess its a problem caused by my home provider?
Any ideas?

Country-locked phone?

Hi there.
I have a friend who has an X1. He is reporting that the X1 is working with his O2 sim card and working on Vodafone however it isnt working with his Latvian sim card (in the UK) (i.e. Tele2 and LMT). Are there any settings you need to change in order to enable roaming? Is it possible for a phone to be country-locked?
Thanks,
Lawrence
It might be the phone is locked..then again it might not be.
What does he see when he puts in the card? How long do you wait while it searches for a signal? (Sometimes when I'm roaming it takes a few moments -in egypt I think I waited 2 minutes - it might take longer for Latvia to register for one or other reason).
thanks for your quick reply!
I dont think it is locked because it works on both O2 and Vodafone fine. I bought the phone from vodafone and all of their phones come unlocked.
its more likely that the phone isnt using the correct setting for the service provider... usually when the phone detect a new sim it will ask you if you want to change your settings... your friend may have missed it and didnt change the setting so it didnt work
Roaming is enabled by the origin network, not by the phone.
There is a chance that some of the UK networks don't allow those SIMs to roam on their network, but you would need all 4 for them not to work.
another reason could be too old incompatible sim card
people have from time to time reported rather old sim cards being
incompatible and solved it by getting newer sim card from their operator

[Q] Constant roaming with local SIM Card...

My Original HD2 got screwed just before Christmas (Faulty LCD and Digitiser).
As a replacement, I bought another one from ebay. Mint condition.
The phone works PERFECTLY in every way except one....
For some reason, my phone thinks its roaming CONSTANTLY, and if I turn off the 'data connection while roaming' then I cant connect to the internet.
This isnt actually a phone fault, but seems to be directly related to the SIM card.
Im living in Ireland and have a Meteor SIM which shows as roaming CONSTANTLY. Tried it with WM factory rom, energyrom, Android from SD card and Nand. All OSes show it as roaming even though Meteor is an IRISH company, and I bought the card in a local Carphone warehouse.
If I change the SIM to a vodafone (Ireland) one, or Tesco one, they show correctly as non-roaming.
Is there a possibility that the phone has some sort of ID which the Meteor Sim is reading but the others cant?
If not, Is there anything I can do to the SIM, or any phone settings that I am missing in order to get this issue resolved. Starting to annoy the HELL out of me.......
What network do Metior use? I had a similar problem with a 3 sim card. This kept coming up as roaming although I was only local. The 3 shop said that if you lose a 3G signal it will show as roaming and transfer you to a partner network ( 3 use orange) could it be similar with your sim?
May well be. The area I am in is low on 3g coverage from Meteor, and drops to Edge.
FINALLY got in touch with customer services at meteor and they hadnt a clue why I should show as roaming, but my bill shows NO roaming charges and infact the account wasnt even set up for roaming.....

can't register on network with g1

I unlocked successfuly my tmobile g1 coming from usa, but now I have no signal and unable to register on network.when I go in settings,wireless control,,mobile networks.when i ask for available networks i have this error message:"error while searching for networks".even when i choose select automatically i have this:"your sim card does not allow a connection to this network".we have GSM, GPRS, and EDGE in my country.Do you have any idea?thanks!
It's your SIM card being locked to a specific network. You might have to contact your vendor.
I don't understand,my sim card locked?I don't have pin code.you are talking about my foreign sim card(non tmobile?)could you explain more?
I don't know why either. I just know that is what happens. I had the same problem with my SIM too when I went on vacation. But I didn't bother trying to fix it. Since I brought the local SIM to use because I didn't want to pay the international rates.

Unable to register phone on T-Mobile network

I've been a T-Mobile customer with my OnePlus 1, got the OnePlus 5 today and went by the local T-Mobile store and got a new SIM card. A couple hours later I got around to actually setting up my phone. I realized I wasn't getting app verification codes, so I called T-Mobile to make sure the SIM card activated properly. She had me confirm the SIM card was inserted properly, then she had me turn the phone off and she "sent it a signal." That got text and data working, but still no go on the phone. She transferred me to the next tier up tech support. On the phone with them, we turned off WiFi, WiFi calling preferred, VoLTE, and automatic selection for Network operators. The phone did it's search and we selected T-Mobile 4G for the Network operator. The phone says it registered on the network, but T-Mobile says it didn't. We tried the second SIM slot but no change. We did a couple reboots and still a no go. I was then told that since it's not a T-Mobile branded phone, they can't guarantee that it will work. They recommend I put the SIM in a T-Mobile phone to confirm that the SIM works - I'll do that when I get home and try it in my wife's phone.
When I turn on VoLTE, I get text and can make calls, otherwise if I make a call, it just calls T-Mobile.
Under Settings > About phone > Status > SIM status, Cellular network state shows disconnected.
I also see under Settings > SIM & network > SIM 1 > SIM name it shows the name as T-Mobile but Carrier says Unknown
Fresh out of the box, running 4.5.3. Has anyone else had any problems getting their OnePlus 5 to register on T-Mobile? I searched the T-Mobile support site but didn't find anything helpful.
I'll try the SIM card in the wife's T-Mobile S7 when I get home, but if anyone has any pointers, I'd appreciate the help.
OnePlus 5 on T-Mobile here and no issues at all.

Same here. I also have 0 issues
Are you using the latest 4.5.4 update for OP5? They had fixes for VoLTE not connecting. Even though I think that was Europe only thing, the download made its way to my phone automatically. If you're not on 4.5.4, go upgrade (it's a simple thing to do)
What are your APNs set to?
Goto...
Settings
Sim and network
Sim x (1 or 2, wherever the sim is installed)
Access point names
Without doing anything besides entering my sim card into the phone and starting it, I have 4 options
If you have anything outside of your current provider, add them. The easiest way to do this is to open up another TMobile phone you have, goto to the same location on that phone and copy settings manually to your OP5.
I did this for my wife's S7 coming from Verizon. Although she doesn't get WiFi calling without flashing firmware (which I'll be doing when she's ready) you shouldn't have that issue.
Bad SIM card
Turns out the SIM card was bad. Went to the T-Mobile store, let the guy double check everything, then he grabbed a new SIM card, popped it in and two minutes later everything was working. I asked him how often he sees bad SIM cards, he said one or two a year.
