Can an IUSACELL (AT&T Mexico) phone be used on AT&T in the US without unlocking? - Android Q&A, Help & Troubleshooting

Can an IUSACELL (AT&T Mexico) phone be used on AT&T in the US without unlocking?
I recently bought a lot of 5 Sony Ericsson Xperia X10 Mini Pros on ebay. I only needed one of them, so now I want to sell the rest of them. The thing is they are carrier locked to IUSACELL, a Mexican carrier who was bought out by AT&T to become part of AT&T Mexico. My question is can these phones be activated on American AT&T in the US without having to unlock them? Thanks in advance.

UK & French Atrix users, question...

I just got an assignment for the UK, France, and Monaco for 2 months (London, Manchester, Paris, Lyon, Nice, Marseilles, Monaco), normally i work in Greece and use an unlocked HTC Kaiser/AT&T Tilt on Wave as the carrier, but now i have the Atrix which i would rather use there, so i gave my Tilt/Kaiser to my sister to use while she is in Greece this year.
I have unlocked my Atrix but dont want to walk into the wifi problems, can anyone confirm a hassle free GSM carrier for an unlocked AT&T Atrix 4G? I will be traveling all over the UK and France and hope to use it for email and map/route purposes.
If not i will just sell the Atrix and buy a phone there and wing it. im actually pretty disappointed in the whole unlocked/wifi thing.
thanks!
Hello,
i have test the atrix with orange and now with bouygues telecom, no problem.
You will not be affected by wifi bugs in those countries. The issues we have on unlocked atrixes arent in fact a byproduct of unlocking but rather of some countries being poorly supported in the driver, that said you should be fine with any carrier in those countries.

[Q] Bell Mobility Compatibility

[+w w w.] ebay.ca/itm/Sony-Ericsson-Xperia-Mini-Pro-SK17i-White-SimFree-Phone-/220839273164?pt=Cell_Phones&hash=item336b0be2cc
I'm looking for the Xperia Mini Pro, but to work on the Bell Mobility Network, and I'm incredibly confused now, how many versions there are of this phone on ebay.
Will the link above be able to work with Bell Mobility?
My friend has the 900/2100 version, and the sim is actively rejected, and I don't want to have that problem =)
Thanks.
afaik the phones supports every band. Could it be possible that you friend uses a simlocked device/sim?
The big amount of these phones on ebay results certainly of the strange way of naming the devices as the previos version was the xperia x10 mini pro. The current on is the same name without x10. Without pro are the devices without hardware keyboard etc.
You should search for sk17i what is the working name of the xperia mini pro and your results should be better
Greetings, Klaus
I don't think it's sim locked because she bought it in Hong Kong, and I can get a 2G signal on it with my Rogers sim card, but when she tries using her Bell sim card it actively refuses it.
I called bell and they said that the phone is not on the same band as their network.
My guess is because Bell doesn't use GSM, but uses HSPDA.
I think the Sk17 has two versions, the SK17 and the SK17i, and perhaps another one. One is quad band, one is tri band and the other is duo band.
To work on Bell or Telus in Canada requires SK17a model, SK17i will not work since as Bell rep told you, the latter is not on the correct band (requires UMTS/WCDMA/3G on 850/1900, the "i" has 900/2100).
Related question—how about T-Mobile in the US? I just bought a Mini Pro, but it seems like it drops the network every couple of minutes before picking it back up. My old G1 used to work perfectly in the same location, so it shouldn't be a reception issue...
Hey there.
I bought a sim locked SK17a from Rogers.
Went to one of those GSM stores in Vancouver, and got a carrier unlock code for $50.
Phone sim unlocked, and can use the Bell network.
Had to manually enter the APN details to access 3G, when I inserted my Bell Sim.

Question about unlocked phones, help please !

Hello All, Looking to purchase the LG V10. The LG V10 is unlocked but a T-Mobile phone and I am concerned about receiving updates. The phone will be used with a Rogers Network Sim in Canada. The phone has been unlocked by the seller and I am wondering if I will receive updates here in Canada with a Canadian carrier ?

Probably not, you will have to ask the original carrier for the sim-unlock codes using the phone's IMEI-codes... Since the phones are so old they should give you the unlock-codes for free. After unlocking them (inserting a sim from another carrier and entering the code) they should function on any other carrier.

question on unlock lg g5

Hi everyone,
I am considering buying a used lg g5 on att network, to use in Europe. Will this phone need to be unlocked to use on a carrier in Europe or will international carrier?
I appreciate the help with this question,

You will need to unlock it through att, but you won't get updates in Europe
