J7 Prime Network Issues - Samsung Galaxy J7 Questions & Answers

I've had my J7 Prime for about 6 months. I bought an unlocked version off amazon Model # SM-G610F/Dual-Sim 32GB & for the most part have not had any major issues. I love the phone but the network connectivity has never been great, even when I travel to large cities. My carrier is AT&T, & the best connection I've ever gotten is H+ . I've never been able to get LTE on this phone which is disappointing because again I really like it. I noticed it says United Arab Emirates in the region. Could this be the reason I'm not able to get LTE in the States? What are my options?
Thanks,
Wes

North American Nexus 5 in Asia

Hi,
I have a north american version Nexus 5 bought in Canada. I will be travelling to Hong Kong and want to use the 4G network there
Am I able to do this or the north american verison cannot use the 4G LTE bands in Hong Kong
Is there any way to flash it or ROM it to change the bands if so?
Thanks
US version should NOT work in HK
If it is only for a short visit, you might have a look for pocket Wifi instead, Many shopping mall offer free Wifi there.

4G of US version (D820) will not work, only 2G and 3G working.
p.s. my wife got the D820 which bought from google online when in canada, so I quite sure about that.

You are indeed correct. Everything but LTE will work just fine.
I have a similar question, but flipped a little for the D821. I want to buy my wife a Nexus 5 phone that will work in both China and Hong Kong -- preferably 4G.
What if I purchase the D821 for use in Asia that, from my research on the 4G LTE bands, will work on 4G in those two countries. Then I bring it back to the US for use. Can anyone confirm whether it will work on US GSM based networks' 4G? I'm almost positive it will not work on either T-Mobile or AT&T, but I can't find much info on any other GSM based network here in the US (which I think use AT&T or T-Mobile networks anyway).
I'd appreciate any help you can offer. I'm still doing research, but there's a good deal going on on ebay for brand new, unlocked D821s for about $375 USD -- reputable Top Seller too. So, I probably need to act fast. In the end, this will be my wife's first smartphone, and so 3G will be fast enough for her, and works perfectly fine in both US and Asia.
THANKS!

3G will work, 4G will not work. Basically the N5 is a world phone except when it comes to LTE, then you need either the North American version or the rest of the world version.

[Q] (Q) MT7-TL10 not seeing all EU/UK bands

I wonder anybody could help with this query/issue I am have?
I recently purchased a MT7-TL10 from the United Arab Emirates whilst on holiday and the phone came preloaded with the latest international ROM (V100R001C00B119SP03). As a result I thought I had an international version of the phone.
When I got back to the UK however I have noticed that a network scan revels that the phone can see both 3 and EE LTE networks (which run over bands 3 & 7) but not O2 and Vodafone (which runs over band 20). Which initially suggests the phone is band locked as UAE only runs bands 3 & 7, though their phones are usually fully compatible with European networks (such as the Samsung S5 my wife purchased).
I don't suppose anybody has had any luck unlocking the bands on this phone or the TL09? Also, there don't seem much logic to the flash the ROM with international version in my instance (which is suggested for the Chinese model) as I am already running it.
I have similar problem in Nigeria. My TL10 could not see band 20.

Don't wait for luck. MT7-TL10 does not support band 20. Check specs.
I bought the gold Mate 7 32gb from Huawei in Saudi Arabia.. and I confirm I don't get 4G on O2. I guess I'll have to change my carrier to either EE or Three. Any recommendation, which carrier would you recommend ? I live in London

I switched to Three as they where offering the best deal plus I had a mobile dongle with them and I knew the reception was always better than O2. The phone now picks up 4G just about everywhere I go.
nice!
there got to be a way to unlock all radio bands.. right? has anyone seen it done ?
I have the same problem with my Mate 7, I've emailed Huawei but they don't want to acknowledge that there is a fault. I suggest you guys also email Huawei!
Huawei Mate 7 TL10 does not support band 20 (800 mHz frequency) that O2 uses. it is not the matter of locking and unlocking, it is that the phone lacks the capability. Sadly enough, I own mate 7 TL10 and am using giffgaff that runs on O2 network.
Edit: This lack of capability is by design. You should check the specs before buying.
I have the Mate 7 TL10 and use in Austria on Three.Three use not the Band 20 at least not in Austria.
My Prepaid Card from Telekom Austria would need band 20,but in larger cities, it also works without

LTE / 4G problem

In quite urgent need of help. Got 2 Galaxy S8+ phones here. I am in Australia. Australian Galaxy S8+ Model I have is the G955F, the other model which I think is USA is a G955U1 or UI I think. It was sold on eBay as an Australian model and I don't think it is after doing some research.
I have noticed that when putting the sim card in the Australian model it shows up on the top bar as '4G' for the network and on speedtest I get a down link rate of 94 mbps.
With the American model I use the same sim card which shows up as LTE instead of 4G and when doing a speedtest I get a rate of 20 mbps.
Bit frustrated about this as it seems it is not able to get the full use out of the frequences here in Australia which is affecting signal, calls and network.
As you lot seem very clued up on this can I ask if you know a fix? Software wise or hardware? Without having to replace the actual mobo and phone.
Thanks

Question TGY or BRI for use on O2UK S9080?

Hey guys
Long time since I've posted on here!
I've just upgraded from my trusty 8GB/512GB Note9 N960F/DS to a 12GB/512GB S22 Ultra S9080/DS (SD) on TGY (from techinthebasket).
The phone is currently on TGY CSC but I'm wondering if anyone knows whether BRI would be better for use in the UK, specifically on O2UK?
I can see 5G is enabled, and there is 5G in my area (my wife can get it on her iPhone 12 Pro on Sky, which is hosted by O2) but I can't seem to pick up 5G on my S22. I know the 9080 only has the N78 band for O2 so maybe that's the issue - if there's only the lower band 5G in my area...
Just wondering if anyone has any experience regarding TGY vs BRI in the UK?
Thanks

I live in Sweden and the net configuration in Sweden and the UK are all almost the same. The TGY or BRI are the same phone just different SW customization, but you will not notice any difference at all.
The 4G support is very good but not 5G, the 5G band support is limited.
If you want to buy a better model, look for "SM-S908E" model. You can find it from Etoren https://eu.etoren.com/products/sams...ual-sim-sm-s908e-256gb-phantom-white-12gb-ram
I don't recommend BRI (Taiwan) or TGY (Hong Kong) if you want to take advantage of 5G. Also the SM-S908E has e-Sim in addition.

Unfortunately the only option for 5G in the UK is with a Exynos variant. Even though your device reflects 5G is enabled and it has the corresponding 5G Band, it's not going to connect. Snapdragon is a much better choice even though you'll sacrifice 5G and Carrier Aggregation and of the 3 SM-9080 variants Hong Kong TGY is your best option.

Thanks for your replies guys, I really appreciate it!
Can I ask, Carrier Aggregation, that's 4G+ isn't it? If so, it's getting 4G+ OK - did a few speed tests earlier and was getting 117Mbs download speeds... Does that should about right for CA? (It's faster than I saw with the Note9 on 4G+ on the same network anyway)

No, Carrier Aggregation is different than 4G+ but if you're getting 117 MBs that's enough for most situations, right? Carrier aggregation is used in LTE-Advanced in order to increase the bandwidth, and thereby increase the bitrate. I can't see rolling the dice on a Exynos variant just to have 5G. And it is a roll of the dice. Samsung's Quality Control is asleep at the wheel.
Something many don't realize, wafer yeild in Samsung's Foundries for the Exynos SoC was a dreadful 30% but it's Snapdragon yeild wasn't much better at 35%. If I were to consider an S22 Ultra it would be after Qualcomm moved it's production to TSMC's Taiwan Foundry in June or July. That will mark Qualcomm's next gen chipset. But even then problems could still nag the device since the marriage between Android 12 and OneUI 4.1 has to date been a messy affair.
I imported a Samsung Galaxy Note²⁰ Ultra from Hong Kong to use on the UK Network.
It was a TGY variant and worked flawlessly.

I think I read a post from you on the same subject on the Samsung forums before I picked up this phone! That's actually the reason I thought I'd go ahead and get a TGY one!
Hi.
Yes I've discussed this on the Samsung Eu forums too.
Just an update in case anyone is interested - I did a speed test (OOKLA Speedtest) comparison via the browser on both my S9080 TGY (12GB/512GB) showing 4G+ on O2UK and my wife's iPhone 12 Pro showing 5G on Sky (runs on the O2UK network) from the same location last night.
My phone got a maximum of 145.7mbs download on 4G+, her iPhone hit a maximum of 53mbs on 5G in the same location. Of course, they could have been connected to different cell towers etc.
The Hong Kong TGY variant is the closest you'll find to a pure android experience on a Samsung device. Less bloatware, best overall network connectivity with one exception. Samsung should modify it's 5G capabilities so it will work on as many networks as possible. Another improvement would allow system apps to be removed or at least disabled, which will likely never happen. Those two modifications would be a huge step forward.

Samsung do this on purpose to cripple devices and stop people from different regions buying the same product. Similarly with their warranties, its only valid and recognized for the country that the device was intended for. A pure anti consumer move by Samsung. Opposite of the evil Apple, whereby their iPhones don't have bands or CA crippled nor do they deny warranty for customers of other regions.
Just a quick update on this, I've just 'upgraded' my O2UK SIM only tariff to the same 150GB deal but told them my device is 5G enabled this time (I was on a Note9 previously). Anyway, tariff change is completed and I now have 5G (Can also see that HD Voice over 4G is active too)

General SM-S908U1 No mobile internet in Europe?

Got a SM-S908U1 I bought in New York directly from Samsung, unlocked US version.
Moved to Europe with it and:
5G, doesn't see it at all
4G, I get like 2Mbps max
3G, nope, shows connected but internet doesn't work at all, keeps crashing
2G, never seen it
I asked the telco, Deutsche Telekom, since they sell the S22 Ultra, and they had no clue, said it should work.
Stock ROM, May patch.
Do I really have to shell out another $1300 every time I travel across continents with a Samsung phone?
What is this ****?
My Pixels and iPhones always worked both in NA and EU.

that sucks, but i think since call recording has been deemed an infringement of privacy and therefore illegal in some countries the csc for your phone is limitied to the bands for the continent of purchase, how old is your pixel ?
what simcard do you use?

I have no issues with 5g or any mobile data/calling issues at all so far in Germany, Czech,or Poland. What provider are you using?
The US s22 isnt compatible with 5g and some 4g Band in germany / Europe...
Im using Hong Kong S9080 In Germany ist the online one fully working
