My bought a N5 32G black in google play USA. but in my country, the CDMA carrier named "China Telecom" does not support N5. when i insert the uim card, i only got a emergency signal.
I think maybe the MEID(ESN) is the problem. So, is there any way to open N5 diag mode and i can modify the MEID? thanks a lot!
No

N00B here! but tried to gather as much info as I could..
Got a VZW droid 2 global from ebay that the seller profiled as "unlocked"
I'm in Central America and trying to register it with a GSM 850/1900 carrier but it won't connect to the network at all.
It had a 14 IMEI code... found it's translation to 15 to 17 IMEI and bought a the unlock code on a site. I got the unlock code but the phone has nowhere to enter it.
Found a post stating that it should ask for the code after inserting a foreign sim card or waiting 30 minutes if nothing happens. tried that and there's no prompt.
I have accessed the testing menu with *#*#4636#*#* and select the GSM only and WCDMA preferred (I got an HTC Inspire 4G working with that one here) and it is recognizing the GSM 850/1900 local carriers but unable to get any network access from them.
Found that VZW locks the carrier's network ids but the phone is recognizing them.
Again: ir recognizes the networks but is not asking for an unlock code... all the posts states to enter the code but they don't say how (the phone must prompt it automatically)
Please let me know if there is any way to manually pull up the field to enter the unlock code or if I can try anything else to unlock it
Thanks!
First, the phone's IMEI is written on the label under the battery.
Second, if you switch it to GSM mode it will output the IMEI in *#06# and in Settings, About phone, Status.
The 14 digit code you mentioned is probably MEID in hex form.
Switching to GSM is done by going to Settings, Wireless & networks, Mobile networks, Network Mode.
Using the service menu you mentioned is wrong and can lead to the phone being unable to connect to GSM at all, in which case you must reflash the SBF.
Actually I got the unlock code but there is nowhere to enter it.
Also it allowed to me to at least view the available networks after changing it to GSM/WCDMA and seems to be trying to connect to one but there's no signal at all.
If I do a network search now it will show me the available networks 5 or 6 (2G&3G), selected one and it just shows that it is not able to connect to that network
BTW, found that the radio was off as well and had to switch it on using the testing menu because by going to Settings, Wireless & networks, Mobile networks didn't allow me to access it at all, it was just grayed out and there was no way I could turn on the radio using that option..... sorry... I think I got everything I need except where to enter the unlock code
It looks like you have successfully (like other people before you) fried the GSM radio settings. Congratulations.
You need to flash the SBF to reset the phone's radio module to its original state.
If you actually bought a phone that was already unlocked it won't ask for an unlock code.
A locked phone asks for the code the moment you power it on and let it boot with a non-Verizon SIM card.
The code you supposedly bought is not for your phone at all, because you requested it for an IMEI you made yourself from something that was never an IMEI.
For me, The unlock screen appear only on original rom with non-verizon sim.
not appear on custom rom.
HELP! HELP! HELP! Just received my new Start S5 Cell Phone - it's a beauty....BUT can't get the GSM phone to work here in Anaheim. Ca. Tried several GSM carriers (ATT, T-Mobile, Net10). Tried both Slot1 and Slot2 Sim & Micro Sim. NO TOWER CONNECTION. I'm only a block away from a tower! Something in the setup or maybe the IMEI is blocked in the USA. CAN ANYONE HELP?
download mobileuncletools and enter the engineermode of your device. you can check the frequency supported by your chipset. these have to match to the carrier you are using. there are some problems in the US, no problems here in europe at all.
Hello all,
I have Google Nexus 5 D821 and I have reset it to Android 5.1.1 using factory image from Google. Everything works fine, but when I insert a valid SIM card, signal strength is 0. When I try to search for all networks available, phone finds no networks. When I select an option to choose the network automatically, I get a warning message that it's not possible for the moment.
I tried entering phone debugging mode with *#*#4636#*#* and there's some information about operator and phone number (probably, it is stored on the SIM card), but phone is always in 'Emergency calls only' mode.
Is there something I can do about it? Is it about hardware? If yes, which component I can try to replace?
Thanks for any advice you might have.
Maybe an antenna cable is loose. Mine had that problem on 3g network.

Cheers !
I have same probleme with white cable antenna on Nexus 5. Changing the cable solved the problem.
its begun all of a sudden
i have try to replace sim . i have checked anntena connections inside the phone.
also i have flushed older version of stock android.
nothing helps
anybody have any idea?
Is it possible the phone has been blacklisted?
it was purchaced in usa and i do not live in usa
I understand but if the carrier subscribes to the blacklist database, that may be a possible explanation.
i do not know how to check if its blacklisted
Open the dialler, type *#06# and enter the imei here: https://swappa.com/esn
hello, I have a Samsung s6 edge+ from sprint (SM G928P). It was working fine with all the carriers in my country (El Salvador) But after a Reset, it did not recognize any sim card. It shows a message saying to insert the UICC sim card provided by my carrier.
The weird thing is that, sometimes, it barely gets signal, but no data. This is just for a minute and then, no signal with any carrier.
Is there a solution? I have the MSL code in case I can use it. I tried to activate global mode , but it did not work.
thanks a lot in advanced
