[Q] Unlocking xt860 for USA

So i'm travelling to the states for 5 days and someone suggested to me instead of paying for a bunch of roaming add-ons from Bell, i may be better off to unlock my phone and get a sim card on a pay as you go plan. Is this possible and more importantly is it worth it?
Any advice is appreciated

I would personally bite the bullet. It'll probably cost you about $20 to unlock the phone and then you will have to get an AT&T SIM card or pay as you go, probably won't have data on it, etc etc... Last time I went down to the US I spent about $50 on roaming. You're only down there for 5 days, how much time do u want to spend screwing with your phone?
Another thing you could do is turn on airplane mode but keep the wifi turn on, and get a google voice number. Pair that with GrooVe IP, and you have a $5 wi-fi only solution.

The data is what I'm more interested in. My phone will double as my GPS unit, and Google search to find stuff to do. Bell charges 30 bucks for 10 MB.
I'm probably gonna e doing 4-5 trips a year to the states, on a pay as you go I could probably just reload everytime I go down, once I have the sim

Just go to Crackberry, go to the SIM unlocking section, find a site that allows you to unlock for free, then yeah T-Mobile has prepaid service, or maybe AT&T I don't know. Anyway, you get the idea.

would this work with tmobile's 4g/3g network?

Stanley,
AFIAK the 3G frequencies used by T-Mobile is AWS, which the XT860 is not compatible with.

Hey guys sorry just a quick question...
Would the Bell XT860 work on Rogers/Fido once it was unlocked? Has anyone actually tried it?
The reason I ask is because I've read that apparently the Verizon Droid 3 was not compatible with Fido/Rogers even after being unlocked.
Thanks

Bell XT860 definitely works on Rogers when unlocked. I'm using one right now on Rogers. (Just running the Chinese ME863 ROM on it right now). When i was on the stock Bell ROM it also worked fine.

I know nothing about this stuff, but google search tells me that t-mobile uses 1900 MHz GSM and 2100MHz UMTS which are both supported by the xt860. They also support HSPA+
does this not mean the xt860 should work on t-mobile?

The phone would need the phone to support the 1700mhz band as well.

Any success with unlocked XT860 working in the USA and getting 3G?
I read elsewhere, it will work on AT&T 3G?
Anyone, please?

All you should have to do is unlock the SIM slot.

I use an AT&T SIM in an unlocked Bell XT860 (and my carrier is actually Rogers) when travelling to the U.S. Everything works fine and I get the H symbol indicator.

Hey fireeater,
I just ordered an XT883 that will be unlocked and will be used with my T-mobile sim. T-Mobile uses 1700 & 2100 for their 3g while AT&T uses 850/1900. Do you know if the agreement between AT&T and T-mobile will allow the XT883 to get 3g with t-mobile?

Tmobile is refarming their 3g. So you will get 3g by the end of the year.

Possible to pick up AT&T LTE?

I was playing around with my T-Mo Z C6606 for over a week.
Yesterday, I decided to flash it with new rom 10.3.1.A.0.244 Generic ES.
I rooted it and it worked properly.
After reading a post about enable LTE in Canada, I decided to flash my Z with C6506 baseband.
Everything is going good and it shows my Z now supports LTE_BC1, LTE_BC2, LTE_BC4, LTE_BC5, LTE_BC17 while stock rom only supports LTE_BC4 for T-Mo LTE. AT&T LTE is LTE_BC4 and LTE_BC17.
However, my Z is still not picking up LTE. I also read that I need to call at&t to update imei to make it connects to LTE.
I called them and they added my Z imei but so far, it is still not picking LTE signals, only H+.
I am not sure if ZL baseband doesn't work with Z or something else.
I appreciate your comments.

I did research and know that t-mobile use band 4 (aws or 1700/2100) for LTE, while at&t use both band 4 and 17 (700) for their LTE.
My Z is now showing it has both bands 4 and 17, but it is still not picking up LTE.

OK, it's ZL baseband issue. I just put t-mo SIM back in and it is not picking up LTE either. I reflash back stock baseband and it picked up LTE right away.
I may have to wait for someone with C6616 would like to create ftf and upload it.

C6603 LTE doesn't work in the US with both t-mobile and at&t. However, you can try flash it with C6606 baseband from t-mobile. It may work.

Can you trying flashing the tmobile model with bell canda firmware? They use lte bands 4 and 17

wolf0491 said:
It works only on one of 3G bands of ATT. Take a look at the map to see if where you live is working well with that band. When I travel I get awful service in places with this model but where I live it works pretty decent. If you have a c6602 though I belive that is pentaband and should work on every 3G band.

I did and only found out C6616 on Bell doesn't have Band 17 either.

Mine is also factory unlocked, but I paid for it. You can check your service configuration by enter a combination key *#*#7378423#*#*
You should only have LTE_BC4.
Without LTE_BC17, you can't pick up at&t LTE.

I am not sure if they have changed their procedure for what phones they allow to use the LTE bands, but from what I read you need an imei of an AT&T branded phone to get them to change your plan to allow LTE access(doesnt't affect the price of your plan) , then you may use a different phone provided you have the proper apn and it supports AT&T LTE bands(which you are uncertain of at this point). Does your AT&T plan online say it's the LTE plan? I currently have the developer version of the HTC One and people had issues getting LTE access on that phone (this phone definitely has AT&T LTE bands) and people had to resort to using a imei of another AT&T branded LTE phone in order to get access to LTE. I previously had a ATT Galaxy Note 2 and when I got my HTC One I just popped the sim in, never called them, and have been fine since.

Yes, I have 4G LTE Plan on my number as it was on my previous Xperia TL AT&T version.
I also did call them and request to add my Z IMEI and they told me they did. However, I couldn't get LTE so far.
One more thing, I also can't get t-mobile LTE with C6506 baseband firmwares unless I reflash it with stock t-mobile baseband (LTE_BC4 only).

From Sprint to TMobile Xperia Z1?

So, I've been hearing Tmobile USA will get the Z1. I'm currently a Sprint customer, so I have a few questions.
1. Will the Tmobile version be lte?
2. Opinions on if this phone is worth making the switch for or if I'm better off waiting till April and using my Sprint upgrade?
3. How is Tmobile's coverage and speeds on the DFW area?
Any help would be appreciated. I've never had a Sony phone but the Xperia Z had me tempted to switch and now with the rumors of the Z1 coming here I'm incredibly tempted.

C6903 has following bands: LTE 800 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600 - C6903
Does this mean we can use C6903 on AT&T 4G LTE?

Only in areas with band 4, which is very seldom for att

does anyone know where the c6906 model might be available to buy?
or if anyone has one for sale?

I know C6903 runs LTE for T-Mobile and the C6906 runs LTE for AT&T. It may depend on what LTE bands AT&T uses for your area so you'll want to check first.

The site may state that, however, it is the C6906 model. The model in the US Sony store is up for debate though, according to their website, it's the C6902 model but that doesn't make too much sense. I guess Sony really doesn't want to market this phone in the US.

Pretty sure this is wrong. D5833 does Not have correct bands for LTE on AT&T or T-Mobile.

Right- it's the other way round- D5803 is US, South America. D5833 doesn't have the required US bands.

Sent from my GT-I9300 using XDA Free mobile app

you can check the bands in which the two models work on. and see if your country and carrier uses those bands. some countries can use either but some countries needs one specific model because of the freq bands used.

That varies by phone model and brand. Apple and Samsung can load quite a few bands in a single model. Sony tends to have fewer bands in a given model, though D5803 has quite a few by Sony standards. I believe D5803 is the model sold in the UK and that model does also work for US LTE.
