Received new unlocked LG V20 from EBay....here in Canada.
Fido sim card worked well in old Viking phone.
When I turn on new phone, I get AT&T stuff so I am assuming it is locked.
I requested unlock code but can't get it in per instructions.
All I get is....Mobile network unavailable.
Help please! Helen
Do you mean that you have AT&T apps on your new device? If AT&T originally sold the device, this is normal, but it doesn't necessarily mean that the device is still locked to their network.
When you insert your Fido SIM card in the device, is the device requesting a network unlock code?
Do you mean that AT&T has already provided you the unlock code for the device?
I only get the AT&T opening banner. It does not ask for an unlock code when I put in my working SIM Fido card. However.....it does say Mobile Network not available. I can put the SIM card back in my
old phone and it works.
AT&T provided me a free unlock code but ......
So...I talked to Fido twice plus technical. They said to phone LG.
LG says the phone is a USA model but not locked. Phone Fido and they say
That is a problem because the settings are in correctly and phone is not asking
for unlock code.
Welcome to the community!
Firstly, these are the band/frequency specifications for that phone:
GSM 850/900/1800/1900 MHz, UMTS 850/1900/2100, LTE Bands 2/4/5/12/29/30, Roaming 1/3/7/20, and CA
~taken from here.
Judging by those specifications, that phone has all of the compatible bands/frequencies for 2G and '3G'. With regards to LTE, that phone has two (possibly three?) compatible bands/frequencies. I'm not sure what AT&T means by specifying the roaming bands...
Have you verified that the APN settings are correct? You can verify those settings here.
In addition, have you tried to enable roaming? Some phones might think they are roaming if they are outside of their intended market even though they use a local SIM.
It does not sound like the phone is locked. However, one of the issues with US model phones is that they can be rather restrictive with their usage off network. Unlike with Canada, each US provider has their own phone variant. There's a reason each provider has their own variant of a particular model of phone. Sure, it used to be that different versions used different systems (ie GSM vs CDMA) and to some extent, that might still be the case in some instances. However, most providers in the US use the same 3G and 4G systems (UMTS/WCDMA and LTE, respectively), though with possibly different bands/frequencies. In theory, assuming the phone has compatible bands/frequencies, it should work on the other networks.
Often the different variants are just to make them more difficult to use on other networks. For example, at one point some Verizon phones needed to be activated on their network before they could be used with a SIM. T-Mobile phones needed to be unlocked via a specialised app rather than using unlock codes. In some instances, phones might technically be unlocked but have certain bands/frequencies or certain functions blocked from being used....
I'm not aware of any specific restrictions AT&T might have put in place on their devices. However, it appears that difficulties trying to use them on different networks is not uncommon (see here).
Hope some of this helps :Smiley:
