I friend offered me the opportunity to buy an HTC Arrive/7 Pro for a very attractive price, without contract, naturally.
Now, I love WP7, and I like my T-Mobile family plan (in the United States). Unfortunately, I'm a totally newbie in the area of using phones on different carriers. From what I understand, I think it's possible to use an HTC Arrive with a T-Mobile sim card, and make calls, but you cannot modify/unlock it to get 3G support, which I do kind of need.
Am I correct? Or am I way off? It'd be great if I could get it working, complete with 3G, with a little work, on the T-Mobile network, but it's just as possible that I couldn't even make basic calls.
3G worked fine (here in Europe) on tested HTC 7 Pro...
if you want use different mobile carriers, your device must be SIM free (SIM unlocked)
So, it would be possible to use my T-Mobile 3G, provided the phone was unlocked?
I've always been a bit fuzzy on the distinction between a normal non-contract phone, and one that is actually unlocked. I do know, of course, that unlocked phones go for a much steeper price then their locked counterparts...I've seen some websites detailing instructions how to do this, allegedly, is this something I could do myself to a non-contract phone (albiet with paying for a code)?
Phone must be unlock (no branding and no simlock). You nothng write about simlock that phone. When device not have simlock you can use everything simcard and everything frequency, but I don't know how work T-Mobile in your country (not from where you wrote) maybe operator locking 3G but i don't think. You must plug in sim card to phone and check that.
Ah, I'm starting to understand, I think. The HTC 7 Pro is, unlike a lot of Sprint's phones, GSM, HSDPA, WiFi, CDMA compatible--T-Mobile's phones are all GSM. I'm in the USA myself.
However, I can't say anything about frequencieis or anything like that. Has anyone ever tried? If not, I may have to just break down and try on the phone first (with an unlocking code).
I'm not sure but I think that HTC 7 Pro and HTC Arrive is the same only difference to Arrive not supported pre-NoDo. You must try plug in sim card and you learn.
On the page HTC specifications wrote that 7 Pro and Arrive frequency is the same:
Network
AT&T:
HSDPA/WCDMA: 850/1900/2100 MHz
GSM: 850/900/1800/1900 MHz
Telus:
HSPA/WCDMA: 850/1900/2100 MHz
GSM: 850/900/1800/1900 MHz

You must try.
Thank you, I think my only option will be to try.
I was able to find some information on T-Mobile's frequencies, but not Sprint's, at the moment.
I'll be able to return the phone, so the cost would be, potentially, the cost for the unlock code (assuming HTC won't give me one for free). I may have to try this out myself.
Sprint is CDMA and the Arrive doesn't have a SIM card (I have the Arrive and know this for a fact). You won't be able to use it on T-Mobile or AT&T.

I was about to say this, but I'll add my hat to the ring and also say there is no SIM card slot on the 7 Pro (Like there was on the TP2).
Though I wish there was. It makes the Photon look really compelling. :/
Really? That's extremely strange, there's a thread on this site showing how to access the SIM card slot and MicroSD slot.

Maybe this is only for HTC 7 Pros outside the US, which are not CMDA?

The guy who made that thread is from Prague, to that's probably the Euro version of the 7 Pro. Europe is mostly GSM. So if you got the unlocked Euro version, it would work on T-Mob, but only EDGE data, not 3G/4G. T-Mobile uses an oddball 3G frequency (UMTS 1700/2100 MHz, also called Band IV), that is not shared by many other networks in the world.

Err, I did a funny. I meant to say the Arrive and 7 Pro for US Cellular.
I have a AT&T Skyrocket and live in a non-LTE area. With the HSPA+ Galaxy Nexus being offered through Google Play for $399 off contract, I'm very tempted to purchase it. My concern/question is will I be able to just take the SIM card I got with the Skyrocket and just put it into the HSPA+ Nexus? And if so, will selling my Skyrocket w/o a SIM make it that much harder to sell?
I have used my LTE sim in my nexus one without any problems. So I would imagine you wouldn't have any either
Sim is backwards compatible, so no worries about GSM & HSPA, guaranteed to work. As for selling with no sim, that's the way its supposed to be done. The buyer should be supplying their own, they can get one on the spot from an AT&T store
Don't give out your old SIM. Your SIM is what associates your phone with your account/phone number.
Got my FIDO Razr HD. Rogers SIM = all is good. AT&T sim = asks for unlock code, which i buy online.
After entering code, phone appears to do a factory reset. During the reboot, a box pops up:
"SIM not allowed MM #3"
Now the phone permits "Emergency Calls Only" with the AT&T sim. Rogers SIM = still good.
When I put AT&T sim into my other phone (HTC desire) it works fine on roaming (rogers network). So I know sim + signal is fine.
Don't understand this error message.
Did I mess up the unlock?
advice appreciated, thanks.
Do you have another Canadian SIM you can try? Bell/Telus etc?

I was doing some research for you, have you tried using a different SIM card from AT&T? The SIM might be corrupted.

Are the SIM cards prepaid or postpaid? Did you have to cut then yourself or were they already micro sized?

If you think AT&T are blocking your phone, then why don't you try T-Mobile...?
... Yes no problem with tmobile or others prepaid carrier on att network...
You just don t roam on att with uour rogers simcard...

Thanks for the replies everyone. to answer the questions:
1) i don't have any other sims right now: just rogers + ATT. Next time i am w/ friends I will ask to borrow telus/bell microsim.
2) they were regular sims that were cut down.
3) haven't had a chance to visit USA since posting topic- but when i do, i will test both cards and also visit an AT&T shop to bug them about it.
Is sim corrupted? I don't think so because it works fine in HTC desire. But I guess trying a new one will prove or disprove.

I want to let you know that I was able to use a Bell sim card in my phone. That's what I used to unlock it with.

I am using this phone with at&t with no problems, I took my sim out from my iphone 5 and used a adapter to go to micro sim and it works fine, no issues.
I'm receiving a Fido RAZR HD to be used with AT&T this afternoon, I'll let you guys know if there are any issues.
OOI, is AT&T seen as a much better GSM network than T-Mobile in the US?
I was looking at the T-Mo USA site, and there are some amazing "Monthly4G" SIM only plans (e.g. $30/month for 100 minutes, unlimited texts and 5GB of HSPA data).
This seems much better value than AT&T, Verizon and even Sprint! But is their network sketchy compared to the others?

AT&T offers the second largest network coverage behind Verizon. They are also one of the two GSM carriers in the United States, and tend to be more popular with mobile phone enthusiasts because their UMTS bands are more common and used with other regions such as Canada or Australia. T-Mobile does indeed offer excellent value, but they use mainly AWS band in addition to PCS band in selected regions, thus making them the lesser choice for using unlocked phones from outside the country.
Hey,
Just looking on wiki:
http://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
It looks like T-Mo mainly use 1900 for 2G and 1700 for 3G, whereas AT&T use 850 and 1900 for both 2G/3G, right?
So if I bought a Canadian Razr HD XT925 and came to the US, would I be able to use T-Mo's 3G network? I am guessing no, since it does not support 3G on 1700MHz.
But then there is a note on that Wiki page saying that they now have a roaming agreement with AT&T after the failed acquisition. So if I forced the phone into "WCDMA only" mode from the test menu, would it then fall back onto the AT&T 3G network?
Sorry for taking the thread slightly off topic
Cheers,
Su

As you have read, T-Mobile did acquire PCS bands from the failed merger with AT&T, but these bands are not as utilized as their 850 MHz band so it's not as widely available as you may think. Some areas might be able to use the 1900 MHz band for T-Mobile 3G, but I would check with fellow T-Mobile users to confirm first before you dive in headfirst. I know that there are T-Mobile users in the Dallas-Fort Worth area that are getting 3G data connectivity with their unlocked AT&T iPhones.
Well T-Mo do daily plays for like 2 bucks right, so I can always try this out before committing to a contract
Do you think AT&T would be the better bet if I am bringing my own device from Europe?
The reason I ask is that I may be coming to a US college for a couple of years, so naturally, I'm planning ahead to see if my phone will work over there

If you're using a device from Europe or Asia, then yes, you have a much higher chance of being able to get 3G connectivity with AT&T. Off the top of my head, Nokia seems to be the only one that tries to actively keep AWS band in their radios.
Hmm, so I did a bit of research on GSM Arena. Seems the Nexus line of devices consistently support 1700MHz 3G (including the Nexus S which I currently have).
Guess who cancelled their Nexus 4 order last week, and opted for a Canadian RAZR HD instead...
Whoops
Anyone know if I can just use the Sim from my Galaxy Nexus in my new RAZR HD and go? Or am I gonna fry something?
yessir, your phone uses a mini sim and the RAZR HD is a "microsim" phone. Several guides online about how to "trim" it. quite easily actually. that being said, newer sims often times offer better features and reception. if you have lte in your area your sim card may not be lte compatible, in which case you'd only get HSDPA + speeds.
Well my GNex has LTE and I'm staying on Verizon. Do I need to contact Verizon that I'm switching phones though?
The sim from my Verizon gNex fit perfectly in the sim slot on the HD without any trimming. I didn't have to contact Verizon to switch and as soon as I booted it up with my gNex's sim card it was active, no other steps required.

Hello, I currently have Sprint in the USA and locked into a contract but when travelling, the service is spotty. I have to take a 2nd phone that I have with tmobile. I understand I can buy like a new Sprint iphone or the new nexus and just swap sim cards and that will work? That is one option. I was also wondering if there is like a single phone that will work with both sprint and tmobile at the same time. Kinda like the samsung duos phones but those only work with 2 gsm carriers. Tried a search but didnt get anywhere. Thanks. Just weighing my options here.

Not with Sprint. As you've no doubt seen, dual SIM phones aren't exactly common in the US. The few that are are imports, and fewer still will even support North American GSM bands. And of course, Sprint uses CDMA for telephony, and only Sprint phones work on their own network. Your only option would be to switch to AT&T and/or T-Mobile or their MVNOs that work on those networks, and find the rare phone that has LTE for both. But if you're sticking with Sprint, you'll either have to swap SIMs on a device that works with any (as you said, iPhone, Nexus...I think the Moto X Pure does too), or carry a 2nd phone for a different carrier.
