[Q] T-Mobile G2 on AU - Vodafone

Hi everyone,
i recently picked up a G2 on a US trip and am currently trying to set it up to work on the AU vodafone network.
i have gone through the sim "unlock" process, so it should be free to accept any sim card. (it also doesnt prompt me for an unlock code anymore, so im assuming it worked)
when i put the vodafone sim card in the phone, it detects the sim (there is the sim folder in the menu, with the vodafone sim options) and when i use "*#*#4636#*#* i see that there is something in the signal strength (-97dBm 8 asu).
BUT
when i goto settings ->wireless & networks -> mobile networks -> network operators i get an error saying "error while searching for networks"
any ideas?

Shouldn't this be in the G2 forum, not the DZ one ?

Thread moved to G2 General.

I am very interested to know how everything works out for you when you get it resolved.
Im moving to Melbourne from San Francisco in 3 weeks and I am on the fence if I should get a Iphone 4 or a HTC g2
*currently own a HTC Evo ..sadly i have to sell it

welcome to the club my friend
Unfortunately we have the same issue as you but we haven't find a solution yet. So far i have figured out that the phone after unlocking cannot read properly CID and MNCMCC codes from sim.

jee... sounds like the club to be in

5 days now i am trying for a solution. So far nothing to say. Just that users with same problem increase day by day. This might be good as htc will have to pay attention.

i dont know if its me, or if anyone else has noticed this, but if you change the band (auto - USA - Euro - Japan - Aus - Aus2)
then go and try to search for networks, the speed that the error comes up is different... its always the same error though....

You are right about that.

hi, i guess i need to join this club .. any progress for the solution?

I'm using a G2 on Vodafone AU and having no problems at all ...
If I click search networks it sort of just stops immediately with VodafoneAU down the bottom.
The one issue I'm having is that numbers are formatted for US ... anyone know how I change this?
I'm not sure if this is a real long-shot but I had some strange problems with my old Vodafone sim in a HTC Magic. I ended up just going into a Vodafone store and asking for a new SIM and the problems vanished immediately. They give you a new SIM on the spot free so it may be worth a try?

Is your phone working unlocked with the tmobile sim? If it isn't you're got the problem a lot of people have been having with unlocking the G2.
Otherwise, try rebooting your phone with your AU sim search for networks automatically and enter your APN settings. Alternatively if it doesnt find networks, go to Vodafone to get a new sim card. I'm also on Vodafone and I'm not having any problems with my current Tmobile Phone (Cliq) and G2 coming in the mail

Fixed by rooting and gfree
Hi! I had this exact same problem: unlocked a T-mobile G2 bought in the US so that I could use it on Greece's Vodaphone network. After unlocking and trying to check for networks, it would just say "Error while searching for networks".
Solution: I found the solution here: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Subsidy_Unlock.2C_SuperCID.2C_and_Radio_S-OFF which describes an extra security measure that was taken on these phones and why you get this error because of it. The fix, described in detail on that page, involves routing your phone and then running a program to change this security "feature".
I followed the directions on that wiki page and it worked perfectly! It now connects to my vodaphone network here, and can see other networks that are around.
Note that as this is altering the software on your phone, it probably voids any warranty. But, I'll say with my US t-mobile G2 it worked very smoothly.
Hope this gives some insight to any others having this problem!

No Manual Selection of Network

Hello I have an odd problem. I have an unlocked ZL which has been working fine on AT&T in the US. I travel to London a lot and have the international data option on my account and has always worked fine with my other phones. However after arriving in London my phone is stuck on Everything Everywhere (EE) and they don't have a roaming agreement with AT&T. This would be an easy problem to solve by manually selecting a different network but this is my problem. On my phone network selection, below, APN is not showing up. I originally thought this may have been disabled by the original network (Indonesia I believe) so I flashed the US generic firmware and Nordic but nothing I do makes it show up. Anyone else have this problem or solution?
Thanks

Its DISABLED by your AT&T sim not the phone. If you notice by putting another Sim (Non AT&T) You can then use network search. Also ANY AT&T Branded Phone Network Search is LOCKED. I know your ZL is not AT&T branded but your SIM is which is causing it to lock it. My disapers when using an AT&T Sim, But when putting a T-Mobile USA sim or Orange UK sim BAM Network search shows up..
Also I think AT&T has Agremeants with EE , as EE can roam on AT&T here in the USA, EE is basically ORANGE UK, If they did not have aggremeants your phone WOULD NOT connect to the network. Make sure your data roaming is checked..

Thanks you are correct. Crazy considering they wanted me to manually select a network other than EE.

They're support is sometimes ehh. If they had never been out of the county they probably won't know. How is it over there . Always wanted to go.

UK HTC One X, no mobile data China Unicom

Hey, I couldn't really find anything similar, so making a post. I have just moved to China and brought my HTC One X with me from the UK. It is a Vodafone contract phone, so it is unlocked but running the Vodafone brand software.
I have bought a China Unicom SIM card, of which calls and texts work fine, but there is no mobile data, it just says disconnected. When I go into the mobile data settings, it has the network operator down as China Unicom and network mode as GSM/WCDMA auto. When I put my Vodafone SIM back in there is also no connection.
It have checked the SIM in someones Chinese phone and it works fine.
I'm not really a phone person, I have never modded/rooted or done anything to change a phone, and my knowledge only goes so far, so hopefully someone can shed some light for me.

Done some quick fact check for this.
Not so sure did Vodafone UK offered HTC One X/XL (edeavoru / evita). However, both of them supporting 3G network frequency operate by China Unicom. Make sure your SIM card has access to their mobile network and have APN set correctly if they are wrong/undectable.

Setting the APN has worked, thank you, I thought I was going to have to buy a new phone

Check this
All I had to do to go to the Access Point Name ('APN') settings and change the Authentication Type from its default 'Not Set' to 'None'. After that, my internet is working fine.
It would appear this may be an issue common to a number of Chinese phones, so hopefully this will be of use to other people in the same situation.
It worked on my star N9599T (whats the difference Not Set and None? but it works!)

Ported AT&T from Cricket (AT&T), nxtgenphone APN gives no data?????

So I jumped on the AT&T/DirecTV Unlimited data deal and ported my phone today. It all looked normal and I got the activation texts and such - it even populated the nxtgenphone APN info (though it was deselected and I had to select it). Anyway, I've had no data at all. As a test, I switched the APN to phone and data works, but the speeds appear to be much lower than what my wife's iPhone is seeing on the nxtgenphone APN. Anyone got any tips?
I'm running Viper 2.5, latest US unlocked firmware and US unlocked selected as carrier, and it works fine on AT&T other than this......only other thing I can mention is when I select preferred band or whatever it shows WCDMA/GSM and if I change it to WCDMA/GSM/LTE it reverts back for some reason. Any help much appreciated. I've called AT&T and they're like, uh, we don't sell the HTC 10 so can't really help you... grrrrrr.....

I'd suggest ruu to stock us unlocked rom and see if the issue persists.
Or, try clean flash of viper.
I have no issues using US unlocked on AT&T with both stock rom and ice.

Thanks for trying to help. I just finished trying stock RUU and same problem. I'm convinced, as I was before, that this is AT&T's issue. I've read numerous posts this afternoon that because the HTC 10 (and other phones) aren't in their "LTE approved" database, nxtgenphone APN won't work, or it will only give HSPA speeds. Seems like everyone who has resolved it, or didn't run into the issue at all had another AT&T LTE phone they could use for the IMEI on the account, or the rep entered the model as an iPhone or similar to make it work. Really, really frustrating, as they refuse to help me and I'm starting to think I should just terminate in the 14 day window and do T-mobile or Verizon.

I have at&t and everything worked out of the box, I've never been on stock rom, always on Viper I did the unlock and s-off without a sim and never had an issue or called at&t to activate the device I just transferred my sim from my note 4 to the HTC 10, no provisioning issues at all, VOLTE works, LTE is fine as well while on a phone call... No issues... If you need anything to compare let me know

Thanks for replying. They did confirm it was a provisioning issue and they fixed it today. They had to do something different, as the default HTC 10 provisioning and IMEI check didn't fix it even when they tried it a second time, but they were able to adjust something and LTE definitely works now. VoLTE working here, too. Thanks!

SIM Card Issue

What happened with my HTC 10 and my SIM card this weekend? I was able to fix it so I'll explain problem and solution. I'm just looking for an understanding from someone smarter than me.
TL : DR ==> Why do two different devices with the same service have locked SIM settings that changed between devices and causing one of the devices (HTC 10) to not have working data?
My HTC 10 is on Viper10 (Nougat Sense based). My wife's phone is a OnePlus3 (FreedomOS (stock based rooted rom on Nougat)).
Both devices are on T-Mobile same plan. We both have T-Mobile so when travelling international we enjoy using the service. Well this is our first trip with both of these devices. We land in Canada and check the box allow data roaming on both phones. The OP3 lights up immediately and has LTE data. The HTC 10 shows no data. I have a signal for voice and whatnot but no data. Going into phone settings it says "disconnected because service is unavailable" under the mobile data toggle. If I go under about phone at the bottom of settings it says LTE but it just refuses to connect the phone.
I don't have much time to mess with this on a vacation but I'm seriously not happy right now. I work though it by trying to swap the SIM cards thinking maybe that's the issue. Nope. OnePlus3 lights up data on my HTC's SIM card but the OP3's SIM card causes same error on HTC 10. I have MultiROM so I booted up a new ROM just for testing to see if maybe it was the ROM causing a problem. I switched to an AOSP based ROM and same problem. No data but I have a signal for basic phone usage.
Now I'm starting to get pissed. I went into the APN section of both phones. They both have a lock icon next to the one supplied by T-Mobile but the APNs are slightly different in their configuration. HTC 10's shows APN roaming protocol as IPV4 whereas the OP3 shows APN roaming protocol as IPV6. I manually created a new APN on the HTC 10 with the exact same settings on the OP3 and BOOM instantly got data working. :laugh:
So to recap from above, why do two different devices with the same service have locked SIM settings that changed between devices and causing one of the devices to not have working data? It wasted a good hour of my trip trying to fix it. If that APN switch didn't fix it I was about to give up and just use the wife's phone for the trip.

Some things you could try...
Deleting apn settings, then hit reset to default. Then reboot phone. Also if you're using T-mobile SIMs they are tied to the device by IMEI. In TLDR seemed like you were trying to swap SIMs.
concerning the data being weird after SIM swap (if they're both unlocked) maybe they have different bands or one has stronger radio.

Thanks for the advice! I had swapped the sim card from my unlocked HTC M9 to a new unlocked HTC M10 and everything was great for a week until one morning it wasn't. I was familiar with creating new APN s when travelling. Followed your advice to a T. Worked first time. I'm currently on the Bell network in Ontario.

Another thing you can try is boot into the BOOTLOADER, not download mode, and do 'fastboot erase persist'

Also note that the command is for S-OFF only devices. And that command only helps when you downgraded the firmware from oreo to nougat or lower. For S-ON devices it works completely different. It has no relation to APN settings.
