hi, I have two phones blackberry priv and zte axon 7. they seem to be unlocked, because when I insert sim card they won't ask for unlock code. originally phones were for Movistar Costa Rica, I bought them on ebay and want to use in europe. but when I insert sim cards they don't get service or any signal, but recognize that sim is inserted and even read sim card number. any idea what can be causing this? btw I can't change anything from secret menu when I call *#*#4636#*#*. please advice me something, thank you very much
someone any advice?

hi guys does anybody know if it is possible to get my o2 xdmini s to except a 3 sim card, it excepts all other sim cards (virgin - vodafone) etc
thanks, jim
Think the simple answer is no.
My understanding is that three use a different frequency and specification - ie wideband CDMA for their mobile coverage, which is not compatible with sims from other carriers using gsm and/or 3gsm services.
If you correctly use the word "accept" instead of "except" in your future posts it will be much easier for people to help you.
one thing that i know is that it will work but no 3g

how? i sim unlocked my G4 mini s. It works with o2, vodafone and should be fine with orange.
But I did check to use my 3 simcard. However, it doesn't accept the card at all. (not only can't use 3G, but no phone feature is available to use)

Q: How do I know my G4 has ever been CID unlocked?

Try SIM Unlocking again. A 3G sim means that it's capable of 3G speeds in a 3G device. I'm currently using a 3G sim in a non 3G device and all is good.
If you didn't CID unlock your device yourself....more than likely it's still CID locked. G4's were only able to be CID unlocked by imei.com or something like that till now. There's a new CID unlocking tool floating around that works on G4's. Give it a try.

Thanks for the reply. But i thought the 3 networks and other networks are working completely different.
I have a sim-free phone. I can use O2, Orange, Vodafone, T-mobile, etc. But when I put my 3 sim-card in. It doesn't allow me to use it. I don't care the 3G speeds. It will be fine to me if I can use the 3 sim card to make a phone call.
The same situation for my Wizzard (O2 Mini S).

i sometimes use a 3g sim and its the same as my regular sim but as long as the sim is for a GSM network it will work but of curse it has to be on a sim unlocked phone

My Wizzard is Sim Unlocked, CID locked. I can use my regular sim cards, like O2, Vodafone, etc.
But why can't I use my 3g sim card to make any call? Any idea about this will be appreciated.
i believe the wizard phones arent made for 3g. so thats probably why your
3g sim wont work.
i emailed imei-check.co.uk and this was the reply
"This is TECHNICAL IMPOSSIBLE. Your device is a 2G device and can handle all GSM SIM cards.
"3" (3G network) does not have GSM SIM cards. They use special U-SIM cards (note the U in front) which are NOT GSM compatible.
In short: To use a "3" sim card you need a 3G/UMTS device which can handle U-SIM cards. Your device is NOT a 3G/UMTS device and thats why it will NEVER be able to use a U-SIM."
that sucks ive got 12 months left of my contract

Exactly, I have 17 and a half months left for my 3 contract.
But the guy "ultraprimeomega" above mentioned, he could use the 3 simcard as well as other simcards. It's very strange to me
Hi, just a quick question because I have been a CDMA user for a long time now and don't have any experience with GSM phones. Is it possible to use a T-Mobile prepaid SIM card in an unlocked HD2 and not have to carry a contract. And if so, what all needs to be unlocked, the phone and SIM or is it an all in one deal?
Thanks,
An unlocked phone could work with any sim carrier ever.
For unlocking, u could buy the unlock code from any unlocking service on the net
Thank you for the response.
Hi everybody,
I bought sprint note 3 wich was locked, and i used ssu apk to unlock it, it was 4.4.4 when i unlocked it, was using with 3g sim cards and i didnt have any issue, now my operator startet with lte/4g networks, and i went to change my sim card and got new sim card with lte/4g support, and now my sim card is not working, when i remove sim and put it again and power on the phone, i have signal for about 1 minute, and i can make calls, then the signals stops, and i changed 2 sim cards, even with other opertor didnt work, what im trying to say is that with normal sim cards my phone works perfect, only with lte/4g sims i cant make it work.. one guy there sad to me maybe your phone is not full unlocked, if this is case how can i fully unlock, thanks in advance and sorry for my english, its not my native language. Again thanks. Any help will be very welcomed.
You need a carrier that has the LTE 1900 GSM band. In the US it's ATT.
I bought a Moto E in Chile several months ago. It came with a SIM card from the company Claro, but they assured me it was unlocked. I switched the SIM to my Entel SIM card, and it worked fine. I took a trip to the U.S. and tried to use a SIM card from someone else's phone, but it asked for a PIN. I just figured the SIM was PIN locked, gave up and forgot about it. Now I'm in Colombia, and I tried several SIM cards from Claro, but they don't work. With my Chilean Entel SIM card, I still get roaming network access, but if I put any other SIM in (even my Chilean Claro SIM), I get no signal. Bizarre because the phone was originally a Claro phone.
So did the Entel SIM card somehow lock my phone to Entel?? That's the only explanation I can think of... If so, how can I unlock it?

Bands might not be supported! That's the best probable explanation since you have an unlocked phone, inserting a sim shouldn't lock it!

I checked that just in case, but the bands are supported. Anyway, if the bands weren't supported I wouldn't get roaming access with my Entel SIM either, right?
The people at Claro (and at Movistar too) told me I need to contact the store where I bought the phone and ask them for an unlock code. Unfortunately I don't have the receipt with me in Colombia, and I don't remember which store I bought the phone at... I guess I'll try just emailing every store I might have bought it at, but if that doesn't work, what other option do I have?
Hi
For my work I use two sim cards from two different countries, and I bought Italian TIM brand of ZE554KL with TIM firmware, thinking that it was DUAL SIM
Even the seller had told me that this phone is dual sim.
Unfortunately, it's not, end there is not any entry regarding dual sim operation in connection menu.
For me this is a problem, because I should use two phones.
I know that many users in Italy who have this phone, have this same problem.
All the two SIMs work well. BUT…
If I want to use Tim sim, I have to put it in the first place in the card tray, or when I have to use Telenor Sim, then I put the Telenor Sim in the first place on card tray.
Simply, every time I should change the place of the sims.
With two sim, one, or no sim inserted, the management of the sim does not exist.
Question:
Is it possible that this phone is different in the hardware configuration for the Italian brend TIM (without internal contacts for the second SIM), or is it only a matter of software management?
I kindly ask you to give me an answer regarding the possibility of enabling the second sim.

Thank you very much.
