So I know when I am not in a tmo area my phone automatically connects to whatever GSM network is available, if any. It's usually ATT but sometimes other regional carriers. However, when I am in a tmo area, it will show ATT as being available, but my phone won't connect to it. Is this a hardware limitation, or is this restricted access controlled by the carrier? If I unlock my phone will I be able to access a different operator?

It won't let you connect because there is no roaming and your own carrier is available. Yes, if you unlock the phone and use another sim you can connect to whatever carrier you desire as long as they are gsm. If you switch to an AT&T sim you will get 2G service only on the G2X due to baseband limitations.
Yeah I knew if I unlocked and used an ATT SIM I could access them. I was just wondering if while I am in a tmo coverage area I could access att while using my tmo SIM like I can while I'm not in a tmo area. As it is now, I can't. I'm just wondering how tmo regulates this. I want to know if there is a way to access att using my tmo SIM while in a tmo area.
Thanks for the reply.

No. TMO and AT&T are direct competitors. They aren't going to allow roaming in areas they have service. I don't even know if they have a roaming agreement for other areas. My guess would be no as AT&T doesn't want to make TMOs service work better prior to the merger.
Oh they for sure have roaming agreements. Anytime I leave a tmo area my phone automatically jumps to ATT.

So this may be a dumb question, but I can't help but to wonder. Is there a way to use different carrier's networks? I know each operate on their own frequencies or ranges, but it seems with all the things you can do with this phone it could be possible. I think it would be amazing if I could use T-Mobile's or Verizon's 4g network, or just switch carriers whenever one had better service/reception. Is there an app for this maybe? Would it require installation of different modems every time you switch networks? Would you have to modify sim card somehow? Is there any kind of information I can read on this somewhere? Any info is appreciated.
You can only connect to the carriers network for whom you have a sim card for.

I know that. I'm wondering if there is a way around that. Verizon doesn't have sim cards right? At least not removable like ATT. Maybe it's just a matter of programming/software on your simcard. I'm just wondering if doing this would be possible. I know how the game goes now, just wondering what stops us from doing this? Aside from the morality issues of stealing.

Verizon gives u a SIM card if u say u are traveling abroad, and want to use their service abroad.
AT&T and T-Mobile along with some others are aa GSM style of network. Verizon, sprint and others.are based on a CDMA network. They are completely different. The only it could be possible if is all the companies 4G networks were the same, such as LTE. Which is extremely doubtful that it will work that way seeing that Sprint is already going Wimax and T-Mobile HSPA+

Didn't know that. I guess I could pay $80 a month to each company. I'm wondering if it's possible to not do that and still get it using only one sim card.
Yes their is. If you have AT&T you can add T-Mobile's APNs along with any other carrier that is GSM that supports your frequency. However, if you switch to that other carriers APN you will be bill astronomical roaming charges.

AT&T is switching to UMTS for their 3G. Same 850 and 1900 bands though. And will be upgrading to LTS for 4g sometime in the near future. I actually install the UMTS cabinets, 850&1900 radios, and coax at towers around here. So there's no possible way to take whatever it is on a sim card that works for a CDMA network and throw it on an AT&T simcard somehow(maybe like a stored contact) and use that programming selectively?

Oh so it is possible, but it's considered roaming? I guess that makes sense. Pretty much what roaming is, using something outside of your carrier.

The sim card ties a phone to a carrier. There is no software to bypass this. Some phones support 2 sims via 2 slots. As for vzw, there sim is a vodaphone sim and only works in other countries as there is no vodaphone service in the us.
If you want multiple gsm carriers you need multiple sims. EU has a hundred different sim cards to support all the carriers.

I have personally use T-Mobile with an AT&T sim card but the bill is not pretty.
I am currently using the phone as a pure wiiFi item. I will be coming out of contract with them and do not plain to get a nother contract. I know that att has a pay as you go for $.10/min with a $15 for 100mb. Belive it or noth that is enough for me for data as I normly only us the phone for about 20 min and 10-15 mb a mounth.
What I was woundering is if I unlock the phone are there other carriers I can go to with this phone so that I can compair? Thank for any help on this.
Yes, when you unlock you can choose any carrier of your choice

Which country are you in? You basically need to check what bands the carrier you want to switch from uses. They need to match what your infuse can use otherwise it won't work.
The phone supports: UMTS 850/1900/2100 and GSM 850/900/1800/1900. I think T-mobile runs on a different band but I don't know for sure as I live in Canada. Here in Canada you can use this phone on Rogers (the carrier that sells it), Bell, Virgin, Fido but I don't think it will work on WIND. If memory serves me correctly it might not work on T-mo, Verizon or Sprint (because Sprint and Verizon are on CDMA). If you are in the US you might want advice from someone other than me though.

yeah but umts bands are incompatible so you still only get 2g.
Isn't it possible to band unlock the infuse, but it requires more than the typical efforts. wasn't some group offering to do it for $50 if you send your phone to them?
Straight Talk. Uses AT&T's networks. But you have to buy a phone off of them with a sim.

There are different types of carriers in America and there are many things scarier can,do to lock certain devices to the network. Tmobile and att are gsm carriers and have some compatibility But they use different bands. The talk works and edge works. No 3g.
Sprint and Verizon are cdma and are not compatible. However Verizon,has phones that are both gsm and cdma and can,work on att. Nextel has Sim cards but are iden. Boost is also half cdma and half iden. And begin is basically sprint.
Then there are the no contract deals like strait talk. Problem is the Sim may be locked to the phone and even if you know the phone has a Sim and is working off atts network it may not work. The strait talk thing is only known to work if you buy a $200 Nokia smartphone and many of those have Tmobile Sims that are locked to the phone. I'm not sure how to tell the tmo version from the att version without looking at the Sim itself. Strait talk seems to just buy rights to use other networks, I've seen phones at Walmart with gsm on the box and others with cdma on the box. I think they use all the major networks depending on the phone.
I also saw an ad for simple mobile. Seems promising but appears to be Tmobile
So no 3g.
In Canada almost all carriers are 100% compatible with att phones. All but one but I forgot the name. So if you're Canadian you have options.
Do not know if you know about this- New T-Mobile Monthly4G $30 Unlimited Web & Text with 100 min of talk
email delivery or purchase monthly cards at Super Walmart.
Can not post link but go to Walmart dot com and search for the card I listed above.. sorry
Consumer Cellular is an AT&T reseller - in fact AT&T phones treat their SIMs as an AT&T SIM, don't even need to unlock.

Thanks, good to know. Might have to look into a consumer cellular Sim and an i777. I wonder if it will work with lte in the future (the Sim that is. not the phone) but I can,worry about that when my area gets lte and the next generation,phone comes out.
So I bought a sidekick 4g thinking I could use my at&t sim card for it and got it unlocked but have one problem. I can only get 2g at the most on my network and asked the service provider who provided me with the unlock code for a solution to this. They told me something about T-Mobile running a different network than at&t and how at&t was updating there network so that I could get 4g on my phone and how it was going to be ready before the end of this year... Is it possible to get 4g yet or any other way around this?

Nope, that person lied to you as well.
AT&T and T-Mobile have different HSPA (4G technically) bands. I think AT&T uses the 850mhz HSPA Band, while T-Mobile uses a different one. Since thats the case, your SIM Card is looking for a band that the phones modem dosent have. Thus, knocks you back to EDGE. Forever.
Hi guys I have a question hopefully someone can help me with. I have the myTouch 4G Slide from T-Mobile but I want to use it on Verizons network. I know how to root and unlock the boot-loader but are there any other steps I need to take before this is functional? Any help would be greatly appreciated.
Version uses sim cards right? If so just search the threads here on how to sim unlock your phone, I believe I read one or two here before. You can also have it unlocked by tmo if your on contract with them or you can buy sim unlock codes

Verizon uses CDMA. The MT4GS is a GSM phone, so there is no way to use it on Verizon's service. It doesn't have a radio that is compatible with Verizon's towers.

Exactly! There is absolutely no way to get this phone, or any GSM phone that I know of, to work on Verizon's system. Even T-Mobile's new LTE service is different than the LTE from Verizon (not that this phone can work on either of those, either).
Haha, couldn't remember myself, hence the foggy reply! CDMA is such a pain, makes me wonder why anyone uses a carrier with it, I mean unless you never travel or want your phone to only ever work with one carrier....

There are a few Verizon and Sprint (both CDMA carriers) that have GSM backup. They market them as their "World Phones". The iPhone5 is one of them. If the phones have the GSM portion unlocked (Verizon automatically unlocks theirs, Sprint will unlock on request after a certain amount of time), you can use a foreign SIM and the GSM radio of those phones. But, you have to be careful, the phones default to the CDMA and if you have roaming turned on, in some countries that could be a VERY expensive oversight with roaming charges.
Hi folks,
I live in a black hole of cellular signal. The only provider that has towers where I live is Verizon. I drive 45 minutes to work every day and over there both Verizon and AT&T have towers. I'm currently using a small, local carrier that uses Verizon towers and phones. I bought a Nexus 6 and want to activate it on straight talk. I thought I could use the IMEI from my existing phone, since it's a Verizon phone, but they say it's not compatible. They say they can activate it as a GSM phone, but I've read that if I activate it as a GSM device, it will not connect to Verizon towers so would basically be useless where I live. However, that doesn't really make sense to me since the Nexus 6 has both CDMA and GSM radios in it.
Does anyone know if I activate a GSM sim and pop it in my Nexus 6 if it will connect to Verizon towers? We do have LTE here, if that makes a difference Thanks for any help you can provide!.
Verizon network will only use CDMA but you could still use it in roaming
