A friend of mine Purchased a Huawei U8150, and bought a carrier unlock code on ebay. When he inserts his sim card he has 2g but no 3g connectivity, in other words no internet. He already upgraded his data plan to android data plan, this is on AT&T. Just wanted to know if there is a way to enable data on this phone.
it doesnt support at&t 3g bands
like my hd2 its doesnt support at&t 3g bands so he cant get 3g on the phone at all its hardware u cant cant so tough luck

Can someone explain why it I've heard that if you take an unlocked AT&T phone like the Fuze to T-Mobile or another provider, that you won't get full 3G data speeds like you do on AT&T? Isn't an unlocked phone "fully" unlocked? What would prevent data from operating at it's fullest?
Thank you! Trying to look online to find a site that will explain this and I'm not getting anywhere.
in usa it depend on what 3g band the provider use vs. what 3g band the phone have
elsewhere it would work 100% as only usa use alternative 3g bands
I recently bought an unlocked Google Nexus S from amazon. The Device works fine on ATT network. When I got it to India and tried inserting an Airtel SIM in it. The phone shows complete Signal strength but says emergency calls only. On the lock screen it says insert SIM.
When I search for available mobile networks it shows my network but unable to connect to it. It does not even ask for unlock code when I insert a SIM from another carrier.
Is this because the phone is locked or is there some other problem?

What network frequencies does Airtel use? If non of them match that could be why, oh and Nexus phones are never network locked

Yeah, frequencies should be the reason here.
But only for 3g, the us always being special, especially at&t. ^^ 2g should work worldwide. Set it to "2g only" and see... (if it works, slow data, but at least you can make calls)
I got a Samsung captivate from ATT and it worked also my Galaxy S 4G. All these are quad. band phones so, they work worldwide. Could be some other problem. Got a good deal, so dont want to return it, but I guess I have no option now.
Tried a new sim?
im gonna be going to india in a month or so and i wanted to know if the i9020a will atleast work with voice in india. airtell or vodafone it doesnt matter. I don't need 3g but i was hoping voice would work so i could just use this phone in india.
did you try to reset the phone?
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.
If I have an unlocked, non-Verizon, LTE device that supports Verizon's LTE network frequencies and, let's say, get a Verizon tablet with a data plan, then put that SIM into said phone, I should be able to connect to Verizon's 4G LTE network through the phone, right?
Hello! I have been at this for a week now.
This is my situation, I bought a fully unlocked dual sim wcdma phone (Mpie 909T) running 4.4.2 KitKat.
I want to use this phone on my straight talk plan, but I only get service from Verizon wireless where I live.
I did some searching and found that I could use a R-UIM card to pick up signal from Verizon BUT I can not find where to buy one at (unless I buy bulk for a couple hundo). So I'm at a loss. I didn't realize that I didn't get service from at&t or T-Mobile till I got the phone and went to the straight talk site and it told me to buy a sim card activation kit, (checked on AT&T site to make sure I would have service and it showed that I would)... so I went and bought the kit only to find out that they actually don't have service out here. ? so if there is no way to find a r-uim card, would there be a way to change the radio frequencies in the phone? But I would also need a MEID # to activate on straight talk CDMA (Verizon towers). Or can I get one of those sim read/writer kits on eBay and program it to work?
I have not rooted the phone yet.
PLEASE HELP!!! I love this phone!!
I've been using the phone via WiFi from my old dx2 that's currently active.
Sadly, you cannot access a CDMA2000 network like Verizon's from a device that does not have a CDMA2000 transceiver. CDMA2000 is technologically incompatible with GSM and UMTS (sometimes called WCDMA). There are some dual mode devices, but Verizon explicitly forbids non-Verizon devices on their network. Even if you could somehow get a RUIM for Verizon, and their blessing to use it, your phone would not work unless it specifically has a CDMA transceiver in it. (remember, CDMA and WCDMA are not the same)
You need a device that supports not only the right technologies, but also the right frequencies. Most Dual-SIM phones are based exclusively on GSM and UMTS/WCDMA, and often operate on frequencies that are not comparable with US GSM operators. AT&T operates on GSM850, GSM1900, UMTS850, UMTS1900, and several bands of LTE. T-mobile operates on GSM1900, UMTS1700, UMTS1900, and several bands of LTE as well. However, most networks outside the Americas use GSM900, GSM1800, UMTS2100, and LTE800, 1800, and 2600.
You can use a site called GSMArena to check which bands your device has. If you want to use a CDMA carrier (Verizon, Sprint, and many rural operators in the US), you generally have to buy a phone with their branding or one of their partners.
Sorry to be the bearer of bad news
I have similar question. Since I am currently using ST with a Verizon phone ( CDMA) could I buy a new phone to replace current one ? And does it need to be another CDMA phone? And what is LOCKED/UNLOCKED have to do with it ?

This is a very large problem. I am in the same boat. Up here, we have Verizon,and ATT. that's it. My first phone here was ATT. worked great in town. As soon as I got to my house dead.,... I bought a Nexus 6 popped the Verizon SIM in it called straight talk they registered me on Verizon's network and boom Full LTE, and VoLTE. My issue now though is I want to try other devices and it seems that the N6 is literally the only non branded phone I can use. There are some awesome new Chinese devices I would love to try and on paper have the correct signals but still claim no Verizon. I am frustrated and stumped after weeks of research and conflicting reports. Does anyone know what is going on? Thanks in advance
