Foreign SIM doesnt prompt for unlock code - Android Q&A, Help & Troubleshooting

I have a sonim xp5700 verizon that is locked, and I want to unlock it. But when I insert a Ukrains SIM I get no prompt for an unlock code. Instead it just says "no service. Vodafone UA" I've contacted several of the online unlock code suppliers and they say without this prompt I can't unlock the phone. I Am I totally hooped, or is there some way I can get this phone unlocked?

Try one of the phone dial codes. Just worked for me but I have a Samsung. AT&T didn't share with me the easiest way to do it... meh, whatever.
Try this...

My bad, skim reading again.
You apparantly only get 10 attempts... so sort this out.
Found this.

Hi
It's not prompting for an unlock code because the phone is not locked. Verizon does lock its phones. The phone is therefore unlocked.
If you read the phone specs you will also see that its a CDMA/LTE ONLY device. It does not have the GSM: 850/900/1800/1900MHz radio. Is Vodafone UA using a CDMA or GSM network?
If its using the GSM network then it will only work on LTE frequencies that the phone supports LTE: B1/B2/B3/B4/B5/B7/B8/B12/ B13/B14/B25/B26/B28/B30/B38/ B41/B66 | UMTS: B1/B2/B4/B5/B8 no GSM voice network.
I had the same problem after I bought the phone and tried it on a foreign GSM network. It would not work.
Please go into Settings -> More -> Mobile networks -> Prefered network type.
You will see it only has these 3 options
* LTE/CDMA,
* LTE Only
* CDMA Only
There will be NO option for GSM
I hope that answers your question. Thanks

[Q] Need help, bricked/nonworking WIFI after succesful sim-unlock

Hi guys,
i used a sim unlock code to unlock the ATT locked Atrix 4g, for use with a european sim card (mobitel, slovenia). it unlocked fine and i could call, but the wifi stopped working it just didnt scan/find or even connect to remembered wifis (home router), which worked perfectly before the unlock. so than i thought it might help to factory reset it, and now the problem persists and i cant even finish the wizard, cuz it wouldnt connect to the cellular (which we have 2g and 3g here) and the wifi has the same problems (so initially it finds all wlans, than after like a few secs it looses them all, i can turn off the wifi and turn it on again and the same thing happens). so i am wodering if anyone has any idea how i could rescue the phone ...
thanks in advance
ok guys i did a hard reset and put in a nonworking sim (doesnt connect to network) and i got the wifi back to working and managed to activate motoblur again. so after that ive put my working sim card in again (3g+ hsdpa+ able), and the wifi stops to work again/behaves the same as i described before. terrible ... anyone has an idea how to fix that ?
ok, more problems, now after ive put the working sim inside and the wifi stopped working, i tried with the nonworking sim (that wifi worked great before with), and the wifi isnt working with the sim it was working before either and even if i try without any sim it doesnt work... ill try with a third sim now and if it wont work ill hard reset it again
Same problem
I have the same exact issue. Anyone know what to do? I can't imagine that this is "bricked" because everything else works fine... thoughts?
where did you guys get the unlock code from?
Actually, I have a similar problem. After entering unlock code the phone accepts my SIM card, but I cannot activate 3G connection. GSM is working, try to call my other phone. APN settings are correct.
In the "hidden" settings menu (*#*#4636#*#*) I cannot chose between radio bands, but only the USA radio band.
Any ideas? Will I need to root it or even put a custom ROM (if it exists)?
So you guys used an unlock code from someone other than the carrier and are now having issues?
Wish I could help on this one. If you used an unlock code from someone other than the carrier, I would contact motorola support.
If you used a piece of software, I would wager that the software broke something and you might as well warranty return it for another.

Don't be offended, but I don't think this is the case. AT&T locked their phone to their network with standard network code (as seen in many other phones for years) so that "alien" SIM card would not work. But, additionally, since the AT&T has some value added services on their data plan (like wifi tethering) they made some accommodations (read: locked parts of the android configuration).
I am not a developer, this is just my guess, but it seams sane and probable.

No offense taken. This is why I asked about a program. Using an unauthorized code to unlock it may over write a.setting or file. Its also possible that someone broke something using adb.
Best solution, warranty it and try again

can you guys tell us what website you use to get your unlock codes from so we can avoid them? thanks
man.. this forum is dead.
even the OP stopped coming here to check his post :/
Based on your replies, I'm guessing you've never unlocked a phone before...
Unlocking a phone to be used for a different carrier affects nothing else but the ability to only use the SIM Card of the carrier you bought the phone from.
To unlock a carrier-locked Motorola phone, you simply need a "Network Unlock PIN" which is an 8 or 16 digit code that you enter to unlock the phone to any network. There is no software installation ivolved in the process.
A 3G issue will occur when your carrier doesn't support the 3G bands that the Atrix supports. Which would be: 850/1900/2100. If your carrier doesn't use any of these bands for their 3G network, then of course you are going to have 3G issues.
The Wi-Fi problem that the OP is having may be as simple as him having an antenna QA issue. But it could never be the Unlock Code.
Unlocking your phone and using another carrier other than AT&T has nothing to do with Wi-Fi issues...

I got my unlock code from cellunlock.net. It unlocked my phone just fine. Don't use that as a reason to avoid cellunlock.net. Unlocking is unlocking.
I have swapped back and forth between my prepaid sim and My AT&T SIM about 5 times so far.
WiFi disconnects almost immediately when I try to connect with my prepaid sim inserted, but I can make calls. (Atrix also displays H+, which can't be right)
With my AT&T sim everything works fine, solid as a rock.
I may do a factory reset to test things, but I have a feeling it has something to do with drivers or the network stack on the atrix, or perhaps because my prepaid sim has no data plan. It certainly isn't a hardware problem with the antenna. I am afraid to do a factory reset on the atrix while I am out of the country, considering that it requires network access to unlock itself.
To the original poster:
When you put a non-connected SIM into the phone, if you do a power reset again, the wifi comes back up solid again.
Also, is there some way we can request a merge of these two threads?

I was merely suggesting that it could be a multitude of things, but never the unlocking code or the process of unlocking itself.
Also, it can't be your SIM because your SIM has nothing to do with Wi-Fi. If we were talking about GSM and 3G then SIM cards come into play. Other than that, no way.
Have you tried using the phone without a SIM? Do you get the same problems?

I agree that it has nothing to do with the SIM or unlocking.
I just tested. I get the same problem with no SIM inserted. Screw it.. doing a factory reset and seeing what happens.
Edit:
Still does the same thing. But now I have to re-activate app sideloading.
Also, you can reactivate over wifi, which is nice.

Unlock For Use In Spain

Hello, I am currently in Spain for 6 weeks for work. I contacted T-Mobile for an unlock code for my phone prior to leaving. I got a sim card today, popped it in and booted up, but my unlock code doesn't work. Does flashing roms have any effect on the unlock code working or not? Any help would be greatly appreciated. Its not easy being here without a phone.
Sent from my SGH-T959 using Tapatalk
What's happening exactly after you boot?
Because I'm also trying to use a Vibrant in Europe and I don't even get to an unlock code... it just boots as if no SIM is in, and doesn't do anything with it (it shows it's in there, but I can't choose operators, join networks etc.).

The SIM you have probably has different bands than what the phone can support. Check GSM Arena for what bands the Vibrant supports. If you are sure its supported, it's probably that the phone can't read the SIM. If it can read it, it will ask for an unlock code.
@ OP: ROM flashing does NOT affect whether a phone is locked or unlocked. The code you were given is wrong then. It could be possible that you wrote it wrong since they spell it over the phone usually. I would contact T-Mobile AGAIN and be a bit upset over getting the wrong code.
Alternatively you can use an app called Galaxy S Unlocker to unlock the phone. But try calling T-Mobile first. It's faster and easier.

What does then (exc. from finding an unlock code)?
Cause I'm stuck, GSM Arena says it's a Quad-Band phone and supports the European frequencies.
Once unlocked, nothing should affect the phone's unlocked status.
I beleive carriers and manufacturers can lock it again but I'm not sure of the procedure. For your issue, GET the correct unlock code and you are good to go.
I was going in circles with T-Mobile. Ended up buying sgs unlock off the market and was unlocked in less than a minute. The T-Mobile support staff are useless.

[Q] Unlocking Rezound for London

After reading the famous thread of the UK guy who unlocked his Rezound in the UK, I am still at a loss as to what I need to do to get this to work.
I am leaving for London next week and still don't know if I am going to 1) purchase an unlock code from htcimeiunlock.com or 2) utilize the Verizon Global program and just use a BB during my trip or 3) try to figure out this whole GSM thing.
I am not a developer, have rooted other Android devices and tinkered a bit, but the Rezound is my baby and cannot afford to brick it at this point. Any suggestions would be greatly appreciated.
You don't have to unlock, root, mod or anything for that mattter. Simply when you're in London pop in whatever sim you bought there in then power on the phone, dial *#*#4636*#*# and select GSM only or WCDMA prefered from the phone information and you'll get signal to make calls and recieve texts.
Data could work out of the box but if it doesn't you simply have to manually insert the APN for your service provider.
But if I used data, won't I be charged astronomical fees through big red? I called their global assistant line and they told me to turn off data and to use strictly WiFi.
This is the confusing part for me, if I do purchase a UK Sim and pop it in, turn on GSM and use my Rezound that way, how will I be charged with roaming and texting?

If you use a local sim card while there then the word roaming simply doesnt apply. No extra fees what so ever, you become a local

Been following this and other threads regarding using a local SIM card in my Rezound. Heading to Bermuda. From what I gathered I can purchase a local Sim, pop it in and use the *#*#4636#*#* menu to switch to WCDMA or GSM and I am good to go? No unlocking necessary? Am I correct?

As soon as you get the 4.03.605.1 OTA, all you'll have to do is go into moble networks and select GSM/UMTS. It should be coming out soon. At least one person has already seen it.

[Q] How to unlock SIM (free) for Japanese Motorola Photon (AU-Kddi)

Hi,
I am wondering that is it possible to do sim unlock for Japanese Motorola Photon (Au-Kddi)?
I am looking for free option (I know that by paying for unlock code, we can do it)
I want following:
I am having Motorola Photon (Japanese version simlock) and I want to use it in India (GSM carrier)
Please help to unlock sim( without paying any money.)
Looking forward to hear from experts.
Thanks.
If you are using your phone outside of the United States you should already be sim unlocked.

Thanks John for your kind reply.
I purchased motorola photon in JAPAN. When I got photon, it was without sim card (carrier Au-Kddi CDMA).
So, I am not sure even it is sim lock or not. (but I think that it must be locked version)
I am planning to use it in India (not in US)
Could you confirm following:
(1) Do I need to unlock it to use it in India with GSM operator?
Looking forward to see your positive response.
Thanks.
As far as I know, the sim lock only applies to US carriers. But, if you're able, try putting a prepaid sim card, or one from a friend's phone in your device and see. You may have to go into settings to take it off of cdma only. I think that if your phone works with any sim card at all, that you'll be able to use it in India. Good luck!

John, your Japanese is good. I am really impressed!!!
As you know that in Japan all cellular service providers are CDMA. So, for me it is difficult to check with GSM sim (because I dont have any GSM sim for testing )
Further more according to my understanding, in Japan all phones come with sim lock. i.e. if I am user of 'Au-Kddi' then I cannot use same hand set with 'Softbank'. (I guess that it is same case as US)
May you provide me some other work around to make sure that photon will work with any GSM provider?

CDMA doesn't use SIM cards... or do they in Japan? only GSM uses sim cards. you will need a GSM sim to test GSM. no way around it with the stock OS that i'm aware of. so buy a GSM sim.

Question Will TMobile sim work in new metro locked n20?

I know with the op n200 metro version you could put your T-Mobile sim in and unlock the phone to work with TMobile automatically, I can't find confirmation anywhere if this works with the n20 as well, does anyone here know?

Was the n20 brand new and the T-Mobile sim inserted before turning the phone on the first time? I read that's how it works on some older phones, I think metro blocked it finally but was hoping it might still work.

yes, I received the phone in mail this afternoon, Brand new and first boot was with T-mobile sim, no service and Mobile network status showed "Disconnected"
The Boot animation did change to T-mobile on a reboot with the sim inside but still no service
As I was playing around with the phone, I stumbled upon a weird way to get signal by trial and error got 4G and 5G data as well but when Wi-fi connected, data seems to switch back to 2G. Let me know if you want to know how

Sure, here it is:
1. Boot the phone with T-mo sim inside the device, once booted you wouldn't have any signal
2. Go to "Sim info & settings" > "Preferred network type" and choose "2G/3G(Automatic)"
3. Reboot the device, once booted you should see signal along with 2G icon
4. Now go back to "Preferred network type" and select "2G/3G/LTE(Automatic)", you should now have 4G (Texts and data works but call dropped)
5. Now switch to "2G/3G/LTE.5G(Automatic)", you should see 5G network (Texts, calls and data all worked fine)
5G was stable for several hours until I connected to Wi-fi and when I disconnected Wi-fi, I noticed that data said 2G.
Let me know if the above steps worked for you

Did you get an incompatible SIM error, or just no signal? Also, you can't just put a Metro SIM in a phone and have it work. You have to call them and tie the IMEI of the phone.

Nord N200 had a bug where the device could be locked to Metro but worked flawless with T-mo sim.
That bug being patched is what OP meant by "blocked"

Yeah, I got that backwards. But if he's not getting an incompatible SIM error with a T-Mobile SIM in the MetroPCS phone and actually getting an edge signal, maybe add a new T-Mobile APN profile. Should work in theory.

Sure, here it is:
1. Boot the phone with T-mo sim inside the device, once booted you wouldn't have any signal
2. Go to "Sim info & settings" > "Preferred network type" and choose "2G/3G(Automatic)"
3. Reboot the device, once booted you should see signal along with 2G icon
4. Now go back to "Preferred network type" and select "2G/3G/LTE(Automatic)", you should now have 4G (Texts and data works but call dropped)
5. Now switch to "2G/3G/LTE.5G(Automatic)", you should see 5G network (Texts, calls and data all worked fine)
5G was stable for several hours until I connected to Wi-fi and when I disconnected Wi-fi, I noticed that data said 2G.
Let me know if the above steps worked for you

Thanks! Good find! Yes I was able to reproduce the behavior. Also in my case it seems that the 5G/LTE will revert back to 2g after some idle time. But I can use the airplane mode to repeat the process (without rebooting the phone) to repeat the process. I was able to reproduce on another metro phone as well. must be some kind of loop hole.

I know I already mentioned this, but did you try making a new T-Mobile APN profile and deleting the old one(s)? Maybe you wouldn't have to go through that ritual. might work, or not.

I just factory reset my device and tried this, deleted existing APN and added T-mo APN, doesn't seem to work
I take it you're not a MetroPCS customer. Must be something baked into the OS. I wonder if it still has the MetroPCS bloatware since it booted with T-Mobile boot animation? Anyway, there are services on eBay that will unlock this phone through the MetroPCS unlock app. I'm not selling anything just letting you know that's an option if you didn't already know.

It installed the T-mo bloatware and removed metro bloatware as soon as it booted. Yeah, I'm not a Metro customer, I'll usually just leave it alone for 180 days and unlock it afterwards

Ah, but you need active service on it for those 180 days to be eligible to unlock it no? And now that it has T-Mobile firmware how can you unlock it from Metro? I'd download the MetroPCS unlock app from the play store and run it to see what it says.

In theory, it's 180 days of active service but in reality, they've been unlocking 180 days after activation. I pay for first month and then throw it back in the box.
Also, I didn't see the unlock app as part of bloatware, its built into settings > about. It'll pull up the same screen as in Unlock app and we can try to unlock from there but obviously, throws the error showing it needs 180 days of service to unlock and is not eligible currently

On eBay it's 75 bucks to unlock. Thats like 2 months of service and you'd be able to use it in a few days instead of having a paperweight for 6 months. Thats what I did on my old Moto One 5G Ace.
