What carriers can use?

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.

Samsung Note

I see Amazon selling the unlocked Samsung Note and mostly all people who bought it are on At&t. I was wondering would this work with Sprint newtwork. I guess At&t and Sprint are on different networks. I saw that At&t guys had to change theie APN.

No. Sprint uses CDMA which means no SIM cards. The note will only work on AT&T, T-mobile, and basically every other network in the world besides Verizon and Sprint.

T-Mobile Note Edge on AT&T.

I have been searching for an answer and have not gotten a clear and definitive answer. Does the T-Mobile Note Edge variant work on all AT&T LTE networks without issue after being unlocked? According to tbr Samsung website both models have the same bands with the t-mobile Edge have 2 additional bands
I have the att model but would really like to be part of the dev community. I have a week and a half to return my att model. I would buy the t-mobile model if it works completely on the networks. Anyone out there using a t-mobile Edge on ATT. Thanks

Think I can help answer a few Qs.
Am using a Straight Talk sim (ATT) in my T-Mo Note Edge. Getting 8-15+ mb/s down...2-4 mb/s up (more than enough for me). Followed rooting method posted by TekHD. Did not see unlock procedure for T-Mo Edge.
T-Mo does hold your unlock hostage for 2+ months or $100 (didn't see this stated and argued). Unlocked through a reputable unlocker through fleabay (~$24 I think - Tmo also recommended...go figure).
Hope this helps.
Wish someone can release a qualcomm kernel w OC/UV/governors and thermal control soon...

Yes, Using one right now. You do not need to unlock it at all it will work right out of the box with an AT&T sim as will all T-Mobile Phones.. This has been a thing for years. There might be some obscure T-Mobile phones without perfect LTE Band or Data support. Every major model will work perfect with absolutely no unlock don't waste your money. I actually called T-Mobile before throwing my gophone sim into the Note Edge T-Mobile variant and cautiously asked if they will blacklist the imei of a phone that is using an AT&T sim. The T-Mobile representative kindly, calmly, and with conviction said that no you will not have your device blacklisted, and that all T-Mobile phones should work out of the box on AT&T. Enjoy not paying for an unlock code! I'll upload pictures of my note edge running AT&T data services via an AT&T gophone sim if you don't believe me. It actually put the APN information in for me automatically too! Meaning I did not have to enter in carrier specific AT&T APN, the software on the Note Edge T-Mo variant picked up the different carrier and entered the APN settings automatically. Woot woot

[Question] Bying a S7 in USA for International USE

Hello guys. I am traveling to USA this week and I wanted to buy a second hand Galaxy S7, from Craigslist.
I live in Brazil, and I was wondering which US carriers I can buy that would work here. (All Brazilian carriers are GSM)
Sprint? Cricket? Verizon? AT&T? T Mobile?
Thanks!

AT&T and T-Mobile are GSM carriers. Sprint and Verizon are CDMA. Also, the S7 model SM-G930U is unbranded, unlocked and supports both CDMA and GSM. Be cautious about purchases from Craigslist. Don't want to scare you too much, but you might want to read this for some pointers about staying safe and not getting ripped off.

i'm waiting for a good deal on black friday in US to use it in India.
Which version to purchase?? kindly clarify

Question How do I use 2 different carriers on the z flip 4?

I currently have a z flip 4 with us cellular and a pixel 6 pro on Verizon, I want to use my Verizon and us cellular number on the z flip 4, kinda like dual sim but the Verizon one as my eim but I keep running into roadblocks, Verizon says it can't be done without closing off my account and us cellular does the same anyone figure out how to get past this?

I am with US Mobile. ( Verizon's MVNO ) I activate my number with eSim with them to get up and running quickly. Then I am able to switch to the real SIM after I receive new SIM order. My guess doing reverse should be the same with US Mobile. I am not sure why Verizon not able to do this without closing account.

On tmobile they set me up to esim, no issue. VERIZON may not be fully supporting esim on androids yet, I had Spectrum which uses Verizon, and they could not set up my esim.
I was on Verizon since cell phones were invented (postpaid, prepaid, mvno), their service and coverage has gone way down hill, now I get 5g where I couldn't even get reception before. So much for keeping a loyal customer happy.

I've had issues with us cellular using an esim too because they want the physical sim to be the main sim card which I think is rediculous, and Verizon just keep giving me road blocks to getting the number ported
