Hello all,
This is a strange problem that I am having with my xda2s while roaming. Origonaly from the UKs O2 network I have taken a recent business trip to Trinidad.
No my way to trinidad I had a stop over in Antigua and Barbados, and in both places the GSM automatically picked up the network and i was able to call, sms and blackberry.
Apon arrival in Trindad i turned the flight mode off and all i got was a no service on the notification. i attempted to set it up manually by setting it to scan and the only network that it found was displayed as '374 130'. I tried to connect but a message appeared saying that it was unable to register on the selected network.
I took my sim card out and placed it in a nokia 6310 phone that i had on me and searched for a network. It found two, TSTT and TTO130. I could connect the nokia to the TSTT network but couldnt to the other.
I am a bit confused why my xda would not connect or even find the TSTT network that my nokia found, as the O2 website states that you need a dual band phone to roam in Trinidad.
I would gladly welcome any sugestions,
M.
here u go
Trinidad and Tobago Digicel MCC setting is 374 and MNC is 130. Bmobile MCC is 374 and MNC is 129. Digicel piggy backs on the Bmobile carrier signal and because of this competition Bmobile has defended and locked out certain attributes.
I have a Verizon TP2 and have unlocked the SIM. I'm heading for Ireland next week and have purchased a prepaid GSM SIM for use in Ireland. Do I need to reset any of the Phone Settings on my TP2 or will it automatically make the changes when I insert the SIM and turn it on in Ireland. Thanks.

i am using sprint TP2, easy switch to GSM network, just go to setting/connection management/phone setting/network
choose GSM ONLY, then system will search GSM network automatically
remember insert GSM SIM card in the phone first
You will have to get data connection setting for the prepaid provider if you want to use your data connection

That is what happend to me with my VZW TP2 in Greece.
Switching to GSM only worked for the phone but I need settings for SMS and Data.
Got the settings but VZW put some kind of lock on the connections settings app. My settings would always revert back to the vzw settings and I would always get connection failur pop up.
Got back home and found online some details about "CMGaurdian"
This program either locks the conection manager or imediately reverts changes back to stock. I think you may need to disable this in registry to enable data and out going sms reliably.
Hi guys,
I have 2 x Nexus S SIM free mobiles which I bought from Car Phone Warehouse in the UK, which we are using now in Spain.
Both handsets have SIM's for the Simyo network (Which is basically Orange's network).
Even though both handsets are unlocked to all networks, I constantly have the roaming icon showing, and I have to enable roaming and data roaming to have coverage.
Now I know beyond any doubt the handsets are NOT roaming.
Has anyone encountered this bug in the Nexus S please, it is really annoying.
Regards
not a bug, simyo has its own network code, which is different from orange's. Therefore, when you use orange's network, it's roaming. Simyo and orange have a roaming agreement, just like yoigo and movistar.
For now, you'll have to enable data roaming for data to work. (there was a discussion somewhere about not labeling it roaming when the country code is the same, which is the case for most of MVNOs)

Thanks for that info. My misses is saying she tried a mates Orange SIM and that it did not show roaming.
However, we also both had Nexus One's, which we purchased here in Spain. Did not get the roaming icon when using the Simyo cards on those...
It is bloody annoying, as we also loose connectivity sometimes and keep having to re-enter the passwords to our google accounts :-\

Ah, you can fix that!
simyo uses dual sim cards (sims with 2 numbers), to make their roaming agreements easier to manage internationally. When you go abroad, it switches from the spanish number to a netherlands one, i believe (though you don't notice it), just like if you changed the sim card.
The thing is, the switch is made when the sim card detects no service for a while. Problem is, that can happen when you lose signal for a while (underground parking, metro, etc...) And what happens when you change your sim card on an android device? yes, you lose google login.
Solution is to lock the sim card to use the spanish number always. You need a phone with STK app (sim menus), and you need to go to Servicio Simyo -> servicio roaming -> seleccion de red -> Seleccion manual -> Nacional. All nokias can access this menu, for example, but stock nexus doesn't have a stk app.
After changing that, hopefully you won't see the login error again. And about the nexus one: it must use a slightly different method to determine roaming, something I don't really know too well.
Woo, OK thank you for the info. Never knew about the dual number thing. Interesting...
This STK stuff, you know of any app for Android mate?
Regards
Hi, just to confirm, I did manage to fix the SIM issue, I borrowed a mates Nokia 1200 and as you said, I entered the STK menu and switch it to Nacional.
MANY THANKS!!
[Q] Why SIM country & operator codes wrong and how were additional APN's installed?
I’m in Ireland, The offices of the Garda Ombudsman (GSOC) was in the papers earlier this year because it was suspected they were being bugged. Also apparently the Gardai have been recording calls to and from police stations for years without the public (or lawyers) being informed. So recording of telephone calls/interception is topical here is topical now.
Wearing my tin-hat, I did a full wipe and installed a Cyanogen-based ROM on my rooted Samsung Galaxy S (i9000). I manually input the correct APN settings for my network operator (48Months/O2-IRL) and I installed Orbot
I never got a network configuration SMS/MMS from the network operator. But somehow, I found also installed (not immediately) were the following APNs:
Eastlink Internet: wisp.mobi.eastlink.ca
Proximus Internet: internet.proximus.be
Eastlink MMS: mms.mobi.eastlink.ca
Proximus MMS: event.proximus.be
It’s a new SIM from when I changed network operator a few months back. The above four APNs were also installed when it came and I queried this to 48 Months with no response. I never saw these APN’s with my previous network operator.
I downloaded a SIM reader app and got the following results:
SIM State - network locked
SIM country code - be
SIM Operator code 20601
SIM IMSI 20601 8816 582453
Phone type - gsm
Network country ID - ie
Net Oper code - 27202
Net Op name - O2 Irl
Net type - HSDPA
Voice roaming - on
Data roaming - off (even though in my phone settings it is showing as on)
So the SIM country code and SIM Operator code are wrong – being for an ISP in Belgium, and also there are those additional APNs which I never installed.
To my simple mind, APN settings are sent by network operators for auto configuration, so these APN’s came from the network operator. However, I have again queried with them and now they say “The tech team have replied this morning to confirm that there is nothing from the network or anything linked with your SIM that would cause your phone to change the settings on your phone.
Due to that they have had no option but to advise you that the phone must be the reason for this.”
But to my knowledge, there are no preinstalled APNs on the ROM (cm-MacKAY ROM Android 4.4.2), and also a 3rd party app can not edit the SIM country code /SIM operator code.
I would love to get an opinion from a developer more familiar with SIMs/APN’s please
Nearly SOLVED
OK, So tin hat is back in its box now...I emailed Eastlink in Canada and they seem to have solved it - very impressive especially when compared with the responses from my network!
"I have had our network team review your question and they have determined there is no security issue and no data traffic that would affect you.
Google has been changing the method that they use for APNs in AOSP. As part of that change APN's are preloaded in Kit Kat. Eastlink's APNs are correctly present in Kit Kat for Home Network Identity 20601.
If you require further assistance with your questions it is recommended the you contact Android Open Source Project or the Cyanogenmod on line.
Thank You for contacting Eastlink Wireless Customer care. "
I came to Japan after speaking0 to sprint about the possibility of using a Japanese SIM card in my phone. They said there'd be no problems I'll just have to unlock the phone before I left which was a completely doable thing by myself without their help. Now once I set up the Japanese sim I can make calls and text but have no access to LTE on my phone. Whenever I'm outside of Wi-Fi range I get a message saying mobile data connection could not be established LTE: ESM - 30 EMM - X I've called Sprint from Japan and tried to resolve the issue, they have walk me through the same steps three different times assuring me that the phone is unlocked on their end and never with a new result. Is there something that I missing it I need to address before I can connect for mobile data connection in Japan with this USA phone.
