[Q] Blacklist Question

I was just curious if I purchased a used Milestone unlocked poped my bell active Bell sim card into it and it works fine does that mean the phone IMEI is fine and not black listed or is this something you can not tell intill you get the phone it's own Sim ? Just looking to buy a used Milestone [A853] for the wife so just want to make sure it's not black listed before purchasing.

I am not sure what you mean by blacklisted. Most operators allow you to run an unlocked phone on your sim without issues. We swap phones all the time at work and Rogers doesn't say anything. There only time i have seen a blacklist implemented was for a specific reason: the rogers htc dream/magic e911 patch. They would blacklist an IMEI until you patched and call customer service.
I have been with fido, rogers and bell and have not hear of blacklisting unlocked phones.

SIM Card will not Allow this connection

Hi Guys...
2 days ago i woke up and found that my phone had no signal. I thought that Rogers (my carrier) was screwing around or something. So i just restarted my device. Nothing.
I checked *#*#4636#*#* and my radio was on (toggled it on and off and on again) and the correct network types were selected (GMS/LTE/CDMA etc. I checked in the settings menu and the correct network types were selected again. Lastly APN settings were all entered for MMS, Data, LTE, etc.
I try to search for the network and it shows Rogers, Telus and Bell. I try to connect to Rogers and i get a message saying that "Your SIM card does not allow this type of connection".
I luckily had a backup from the day previous which i restored. No go there. I did a full clean wipe and install of Viper One RC2 and then a random AOSP-based ROM, again nothing.
the weird thing is that in the Phone Information menu the device reads my phone number and IMEI easiy, so its not like the phone isn't reading the SIM card...
Has anyone encountered this problem or have any suggestions? I have seen this error happen with other devices when i Googled it and searched XDA, but no solution or resolution, and definitely nothing specific to the HTC One.

Did you buy the phone new or used? I've seen this happen to people who bought used phones on ebay. There's a scam going in which the seller will wait a month to get outside the return period and then report it stolen. They get the $$$ and a new phone, and you're screwed.
If you bought it new, your sim card might be damaged.

I wish it was a SIM card issue, but it's not. I tried the same SIM in my Nexus 4 and it works just fine. My sister has an iPhone 4S, I swapped the SIM from it and it didn't work either.
The device itself is a Telus device unlocked that I bought locally brand new from a seller off of kijiji. The device was completely untouched and wrapped in all the right ways. I bought it back in June I think.

It may have been a brand new phone that the seller bought and immediately put up for sale.
You need to talk to Telus to see if the IMEI has been reported stolen.

So the device is definitely blacklisted in Canada...Rogers is saying it's Telus that blacklisted it. Telus is saying they never had the device in their inventory (IMEI doesn't show in their database), so it isn't their device and they didn't blacklisted it. Bell said they had in their database and its a deactivated IMEI, so...I'll be taking a trip to several corporate stores to get this sorted today.

Should my HTC One work anywhere in the world?

I bought my One in the UK and, as far as I'm aware, it's locked to Three (the network I bought it from). Since I've come to China and South East Asia, I do not get any signal on my phone. My girlfriend who has an iPhone 3Gs and is also on Three gets signal (or she did before she cancelled her contract).
Should I get signal out here? I thought the phone would be able to work anywhere in the world in spite of where it was purchased. Anybody know anything about this? It's rooted and I have a custom ROM and custom firmware installed. Pretty sure I also updated the radio manually too, but I can't remember.

Its not working because the phone is SIM-locked to Three network. You will have to SIM unlock the phone.
http://support.three.co.uk/SRVS/CGI..._cat=billing,varset_subcat=3772,Case=obj(4363)
Request an unlock code and continue the process. Then, your SIM will be unlocked and you will be able to use it anywhere

Huh, I thought that would only happen if I tried to put a non-Three SIM in the phone. Thanks, man

If you have your UK SIM in there, maybe you need to activate roaming on the network. But you know what they're like, you can only do that whilst in the UK.
Get an unlock code from eBay or a website and buy a local SIM, it'll save you money in days or even hours given the stupendous price of data roaming.

[Q] Unlocked ATT Moto X on Tmobile no service

Hey guys, I bought a second hand AT&T Moto X 2014 off ebay about a week ago with a clean IMEI. I unlocked the phone by buying a code online, but since then have not been able to get a stable signal. I purchased a new TMobile nano card, and had it activated. I'll get cell service for about 3 minutes, and can make calls, send a text... then the phone will get no service whatsoever for the rest of the day. I'll get surprise pockets of service for several minutes once or twice a day.
I spent some time with the TMobile technicians, who have registered the IMEI, have done a master restore (not sure what that meant) sent several signal downloads to the sim, and ultimately said the issue is with the phone. I also tried my wifes ATT sim card and rebooted, still resulting in no service on ATT either. The Moto X is running 5.02. I've tried messing with the APN settings in various formats that I've seen online. My new sim works with my Nexus 5 perfectly.
I contacted the ebay seller, who is willing to refund 50% of the purchase due to unlocking the phone online. Do I pretty much have a bricked phone? I can't seem to find a solution and have gone back to using my nexus 5 with a shattered screen.
Thanks for the help.

Try changing the network from gsm/LTE (default) to wcdma preferred. I found the phone to pick up better signal when I change it to wcdma. Download the app secret phone info from the playstore. I also have the at&t variant and I unlocked it buying an online code and it works flawlessly with my carrier

Thanks so much!!
After having tried reflashing to stock, fastbooting just the radio, doing numerous factory resets, downloading the app you suggesting and switching the networks gets me reliable cell coverage! Now I just have to work on figuring out how to get data coverage.
Thanks again!

How is the world did you know to do this? This happened to me after I unlocked my AT&T XT1097. Once unlocked with T-Mobile SIM, the phone no longer shows any service with either AT&T or T-Mobile. Very frustrating, was ready to send the phone back and luckily decided to Google and of course, this is exactly what the issue was. THANK YOU, THANK, THANK YOU.
Why is this even an issue with this phone? Makes no sense. You truly saved the day.

Getting the unlock code
Can you guys please tell me where you got the unlock codes from? There are a bunch of sites online, and I don't know which one to purchase it from.
Thanks

Network unlock?

Hi all. My friend got a new P20 Pro, which he though was network unlocked but it isn't. Is it possible to unlock? Do the many unlock sites work with this phone? Any recommendations if so? Thanks!

I am also looking for a solution as I am due to travel to asia next month. Mine is locked to EE. I can carry two phones but I really wanna avoid this for safety reasons and also because when holidaying i'm always carrying other valuables like passports, cash, external battery bank, sunglasses etc etc.

A network lock does not mean it cannot be used in another country, you can still travel else where and use the phone with locked network, well it's actually called SIM Lock not network lock, when SIM is locked it means it only accepts 1 provider to be used on the phone. But when you travel it can still borrow other networks systems so you will still be able to call and send sms and such as you can do now.
So let's say you live in UK and got provider called three and it's locked to three, then when you travel to asia it will automaticly borrow one of their network somehow but it will etc say three (vodafone) on the phone, that means it is borrowing network through vodafone in asia but billing will go via three and not vodafone. since vodafone will bill three and then three will bill you for the sms, calls and such.
Answer to OP: easiest way is to go to provider where your bought the phone from and have them unlocking your SIM lock on the phone. But it would cost you money for it thought. But be aware, if your phone is under a subscription deal then provider will reject the SIM unlock. Since they don't want you to try use another provider or try cancel current one while you got phone from them cheaper under a subscription. So this is why SIM lock is set on the phone to avoid this. But you can still use other networks called roaming with same SIM card, like i explained further up how it will go when you travel.

Thanks for the reply, Jake. I was hoping to use a local sim on my holiday in Asia and then to Egypt... as data is a LOT cheaper using a local sim instead of roaming on my UK EE sim. If it is network locked, it would mean I cannot use a local sim abroad, correct?

never heard of something called network locked, but i have heard of sim lock. sim lock is diffirent to network lock, it means you can only use carrier you got phone off. But it will still use function called roaming what so ever when you travel to be able to connect to your carrier through other carriers systems.
So try asking your provider again is it network lock or sim lock. They could of meant sim lock and not network lock. If they say this then you are good to go and can use your SIM card anywhere, but then it will show on phone something like Three (Other operators name) since it will automaticly borrow through another carriers system. But you will be charged via your local carrier for the calls, internet use and so on.

So as stated, mine was locked to EE and they wouldn't unlock it.
I used https://www.unlockunit.com and got some unlock codes in less than 24hrs. My o2 card now works!
I assume now it's sim unlocked, that any card from any country would work. But that's a guess on my part.

This is very exciting! Your EE locked P20 Pro got unlocked using a code from that website? Now you can use an o2 sim in it?
Please confirm.

Yup! That's what happened. Basically, a friend purchased the P20 from a third party site (ie, not EE) with the intent to sell it (to me in the end). He assumed it was unlocked, which it wasn't on arrival. EE wouldn't unlock it until 6 months in.
I put the details into that site and honestly expected nothing. Less than 24hrs later I got a bunch of unlock codes, first one worked. Very happy

they even don't have mate 20 pro on list just mate 20 lite.
So it's impossible to take out simlock with this fake site

Network / SIM lock, same thing.
Basically you just want to use another SIM than was originally intended, for travelling purposes or for if the phones sold and the buyer wants to use another SIM.
There are a tonne of services on the high street and online, eBay etc who can do this.
Should be quite cheap.
EE will provide it for £20 so long as the phones over 6 months old. Least that's what it used to be.
They can do it for free but you'd have to sweet talk them.
It's your right to have it unlocked, mobile networks shouldn't be able to lock them down, certain shops like carphone warehouse offer unlocked phones so I'd recommend buying from them in the future.
OEM's also offer the device unlocked.
