I'm getting full Signal bars but no 4G/3G/LTE - AT&T Samsung Galaxy S7 Questions & Answers

Hey everyone. So I recently upgraded from a Sony Z2 to a new gold Galaxy s7 flat. So I recently bought it new from a retailer known as Vodacom (Vodafone) in South Africa. I was asking the guy working there if the phone is sim unlocked and he said 'Yes.' Well i did have a few vodacom phones before, working with other carrier sims overseas, so i trusted him and bought the phone. I live in New Zealand and I was on a flight to nz the same day that i bought the phone (Because in South Africa the s7 is much cheaper + you get a free Galaxy tab 3 lite witht the deal). So when i arrived in nz, i got me a Vodafone (Not vodacom) sim card and inserted it ito the phone. I got full signal bars but no 3g or 4g or internet in general. When i booted the phone up, it didn't ask for a network code or anything, and the Vodafone SIM app did suddenly appear on my phone, so I have no idea what's really wrong with this thing. My mobile data is on and limit are all off. Please help me!

[Q] Confused about Region Lock (Verizon)

Hello everyone,
I have a verizon note 3, bought it in october so I've been using it for some time now. I am going to travel to asia in a couple of days, question is am I going to be able to plug a local sim card in from (e.g china) and expect it to work? All the articles online about region lock is making the situation more confusing. I just want to know if I am able to use a sim card in asia on my note 3, having been using the phone for the last couple month here on verizon already.
Thanks,
my note 3 is same 2,, buyed from ireland as europen phone but used for turkish sim card and work well..

Problems with network connectivity

Hi guys, thanks for reading the thread. I know I am fresh here but hear me out.
I actually did have an account but for the life of me cant get back into it, its 2 years since i was on here.
Anyway i bought my sammy (Galaxy Grand Prime SM-G530M, Android 5.2.0) In Colombia after getting 2 phones stolen off me cos of my Gringo`ness.
I bought it "secound hand" as I couldnt afford anything new. Used it with 2 different cellphone providers Claro and Tigo and it worked fine which is why i figure it is not locked to a certain companies simcard, although later on i did have trouble using it with Tigo but it initially did work.
So I brought the phone home with me to New Zealand and stuck an NZ sim in it and it says no service network unavailable. After taking to the shop of the company who`s sim i tried (2Degrees) they said it needed to be network unlocked. To my understanding that means it needs to be unlocked to use on the New Zealand network which involves registering it on the New Zealand cell network data base. Please bear with me ass I know nothing of what i am talking about.
I was quoted $60 which is too much for me as i am a broke traveler. So I was going to use FastGsm to see if i would work but have decided against it as have some concerns about using thier site.
Please let me known if i am totally misguided or if there is a simple solution to this
Thanks
Anyone?

Kernel and bandwidth ranges

I bought a Samsung Note 3 couple of years back when it released in Saudi Arabia. Brought it to Bangladesh but the phone wouldn't work since it got region locked despite me buying an unlocked phone.
I took it to local repair shops and whole they did manage to unlock it, I'm not quite sure how they went about it. I can't use 3G on the phone here in Bangladesh and only 2G works.
I went to Canada and the phone didn't work there. Tried Bell I think and it didn't work. I also went to Malaysia and nothing worked there as well.
So my question is this, did they somehow change the bandwidth range availability or something on it? Can it be re enabled flashing a kernel or am I asking something dumb?
Modem/baseband and CSC for network .
Depends upon what spectrum the network uses as well .Also depends upon phone model .

Check the model # in download mode and post it here. Every note 3 should work in Canada in the Bell network @ 3g. Bell does not have a 2g network.

Huawei Mate 9 Pro Dual SIM

Hi,
I am looking for a good quality Dual SIM mobile so I would like to ask you about couple of thinks:
1. Does the Second SIM can work with 3G instead like P9 Plus only 2G only? I know data can be only from one SIM but calls from two. Here in AU there is no 2G
2. Does it worth to buy it?
Regards
On a recent trip to Taipei, my AT&T global roaming SIM was my primary (4G on Chunghwa network) while my China Mobile SIM was secondary/phone only (3G on 大哥大 network). So, I believe the phone only secondary SIM is capable of more than just 2G.
However, this looks to be network dependant as when in China and the AT&T SIM is my main driver, the China Telecom SIM stays on 2G.
Thanks for info. I have confirmation from dealer that SIM2 can work on 2G/3G but I am confused because in user manual there is information that second SIM can work only on 2G'.
Can someone confirm it in practice?
Regards
Second SIM should support 3g no issues, see attached screenshot
Is the phone full active or stand by ..
very happy with my mate9 pro - dual sim. LON-L29C636 working great on AT&T in the USA. Only one sim (you can select between SIM1 and SIM2) is for data. I was in the middle east and asia the last few weeks and dual sims worked great (I have AT&T and Singapore (Starhub) SIM's in my phone). This was my note 7 replacement and I've been very happy with it. Amazing battery life and supercharging is fast (but you have to use their dedicated charger/cable or you just get regular charge speeds). i bought mine off ebay (it's a UAE model) and had no problems.
quick question
I am looking to get the mate 9 pro
Are any of you on Tmobile in the USA, and, do you get 4G/LTE?
The reseller I have been emailing with on Amazon says you do NOT get 4GLTE on Tmobile in the USA with this phone, but I have read that you do.
Thanks if you can help with this! :good::good:
