MetroPCS and no-name/clone Chinese phones? - General Questions and Answers

Has anyone tried bringing random unlocked Chinese phones to MetroPCS? They seem to support unlocked GSM phones but i've really only seen it used with like, flagship from other US carriers.
If there's anyone who has done it, how does the network behave with your device? Purely curious.

Purchased a Leagoo Elite 5 phone from China was able to connect with metro pcs but only with 3G service. Tech rep told me that not all phones from China will be able to connect to metro and get full 4G service and the only way to find out if any particular phone will work is to purchase and try to connect. There is no master list from metro of which Chinese phones are supported on their network.

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.

Do dual network Phones Exist?

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.

International vs. US model

I am on AT&T in the US. I'd like to get the 6GB version. I haven't seen that it is being offered in the US. Anyone know if it will?
Assuming it will, ifs there any specific reason to purchase the US model over the international version? I would like to have a phone that will work on both Verizon and AT&T, as I may change carriers.
Any advice?
The Mate 9 will not work on Verizon nor Sprint. Its a GSM phone which means AT&T and Tmobile
If you're changing, then consider T-Mobile!
Not sure you guys realize Verizon uses SIM cards now too on some phones. Pixel XL is a sim card phone that was sold exclusively for a min through verizon, my friends have Nexus 6P on Verizon network. Sprint also uses a nano SIM on all their iPhones. Now the bands they support maybe different from a US version to a International.

I'm waiting for the official US release in the scant hope of VZW radio support. (Not likely though)

Oh, interesting. That is a caveat that throws the consideration less toward this phone.
Thanks for the replies.

Yes, if you get a variant of the Mate 9 that supports Verizon's LTE bands it will likely work for LTE. However it will not support 3G, 1X, or voice (which are CDMA). The Pixel and Nexus 6P include CDMA support, which the Mate 9 does not.

The Kirin 960 natively supports CDMA. But whether or not it gets certified for use in the US in the Mate 9 is yet to be seen.
This is killing me. I'm on Sprint, I want this phone. I keep hearing multiple different things. I want to order an international one to have ordered one by the end of the year. I see multiple models (MHA-AL00 and MHA-L29) hoping something will work with CDMA (Sprint)
They likely won't bother supporting all the right frequencies unless VZ or Sprint brands the phone, which seems even less likely... VZ has been using sims since LTE rolled out but that isn't really the problem.
If you're on a AT&T or T-Mobile then who cares about the US model... The only benefit is that eventually there will be cheaper used phones in the US after 6+ months.
I have a MHA-AL00 (6gb, 128gb) from China and wish I had an AL29 as the Chinese support on unlocking the boot loader is terrible (e.g., I cannot get a code). AL29 is supported by one of the apps and also I believe local Huawei offices. Installing google play thankfully is not a problem but I'd be careful nonetheless on the AL00.

Verizon and Sprint only use SIM cards for international use, they had to use/include GSM in order for their phones to roam outside the US.

Purchasing Note 9 "unlocked" but cannot be used on Sprint?

Hello everyone,
I am looking to buy an Unlocked Note 9 (US Version) to be used primarily on the Sprint Network. I am looking at new phones on Ebay and Amazon and they are all labeled as GSM unlocked or some of them say GSM and CDMA unlocked, yet they all say they cannot work on the Sprint or Metro PCS or Verizon network. Some of the ads show that they have SM-960U1(unlocked) firmware some others show SM-960U firmware while still stating "unlocked", but I am not sure if they understand the difference or maybe I do not.
Aside for the phone being blacklisted on these networks, is there any other reason why a Note 9 would not work on these CDMA networks if they are truly unlocked? Thanks in advance.

If you're going to be using the device primarily on Sprint, why not get an unlocked Sprint version of Note 9? It is guaranteed to work on Sprint's network plus if it is unlocked, it can be used on other carrier networks.

Hello Droidriven, I am trying to look for this, but I am unable to. I have not seen any ads specifically stating Sprint Unlocked. Every unlocked phone whether GSM or CDMA unlocked states something along the lines, will not work on sprint or verizon or metro. If the phone is truly unlocked and supports the CDMA bands that Sprint uses, then what is the reason behind it?
I am wondering if I can just buy a Sprint only Note9 then flash the SM-960U1(unlocked) firmware for it?
I went through the same issues with sprint, got a note 9 unlocked from a friend an they said it is not compatible. So I asked about buying a note 9 unlocked from them. I asked what is model number and it was the exact same as the one I just got. I asked what is the difference between one from them and the note 9 I baught from my friend, They said no difference, EXACT SAME! Sprint Just wanted me and you to buy a new phone from them in a contract. The Unlocked model's have modems for both, CDMA and GSM. I was with sprint for 20 years, they were decent only for good deals, service was **** in Milwaukee. I left them for spectrum. No issues and great service. Sorry 2 years late..

VOLTE On TMobile & ATT?

will volte work out the box for TMobile ? They won't activate phones on their network after a while if they don't support VOLTE.... Or any plans to update it in the near future. When will this go on sale in North America?
Sent from my ASUS_I01WDX using Tapatalk
I am currently on T-mo, it doesn't do VoLTE currently, I know its possible via root and changing parameters. ALSO they just enabled VoLTE for their ROG phone 3 via an update so I will assume they will probably do the same for the ZF7, if not I will have to root it.
I asked an asus rep about sale in NA and they didn't have an answer from marketing team, so I bought mine on eBay
I'm beginning to think they will sell in in america especially if they enable volte for TMobile like they did the rog 3. I'm waiting to see if they enable volte on the 6 and the 7.
And then there's the OnePlus 8T coming in going to weigh my optione

This guy apparently has VoLTE already on his phone, unsure how though.
Will this work on att in the states? Also which model if so?
ATT will ONLY work upto 3g. You will see an H on top the signal bar which indicates a Enhanced 3g speed also know as HSPA speed connection. I have tried 2 new sim cards. I have tried several APN's I have tried all updates and a reset. No 4G and no 5G on ATT. Unless someone can tell me something new, this phone will not FULLY work on ATT. Text works. Calls work. Internet is sort of hit and miss with decent signal but again rather slow.
T Mobile will ONLY work upto 4g. No Volte although it seems to have the capability of Volte it cant not work with Tmobile Volte because it seems the cell bands are not compatible. Text work. Internet works rather fast, Good solid signal however no 5G and no Volte due to incompatible cell bands.
I did research on this subject and found that the ATT cell bands for everything including 5G do seem to be compatible with the 7 pro but again, it does not FULLY work oddly
I also did research on Tmobile cell bands and the bands for 5G are not even close to being compatible. Volte is also non compatible. 4g is compatible and works..
THIS IS MY OWN PERSONAL EXPERIENCE TODAY AS I PURCHASED A SIM FROM EACH PROVIDER ( THIS IS A DUAL SIM PHONE) AND PLACED THEM BOTH IN THE PHONE.. I DID EXTENSIVE RESEARCH>>>
IF ANYONE CAN GET THE PHONE TO DO 4G or 5G ID APPRECIATE THAT INFO>>
ASUS NEEDS TO DO AN UPDAT FAST BEFORE PEOPLE START TO RETURN THIS DEVICE. THIS AGE IS ALL ABOUT 5 G.. THIS PHONE IS NOT COMPATIBLE WITH USA. I DO NOT SEE HOW AN UPDATE WILL FIX THE PROBLEM SINCE THE PHONE IS ONLY PHYSICALLY CABLE OF A SPECIFIC SET OF BANDS WHICH ARE NOT NOT NOT THE SAME AS USA BANDS
