[Q] Verizon phone on ATT network questions - General Questions and Answers

I have a Samsung Galaxy S4 Mini from Verizon (Model SCH-I435). My boss gave it to me since I needed a new phone and to my surprise, it was unlocked and I was able to get it working with ATT. My only problem so far is that the data speeds are not what I was expecting. I only get 2mbits/s when compared to my company phone (which is verizon) gets 10mbits/s. My thought was that the phone could did not support ATT's 4g/LTE network but from all my research, it looks like it should. When testing the speed or using data, it shows shows "H+" at the top of the screen.
Here is a list of supported networks from Samsung's website for the SCH-I435
Frequencies and Data Type Digital (CDMA/PCS)/1x, EVDO Rev A; Global(GPRS/EDGE/GSM(850/900/1800/1900); HSPA/UMTS(850/900/1900/2100), LTE (Band 13, Band 4)
Judging from wikipedia, Att uses band 4 and it says the phone supports band 4 so I do not get why it is not going faster. Any help would be appreciated.

You need to have LTE enabled in your AT&T account otherwise it won't let you connect with the LTE APN settings (you'll need to make sure you have the LTE APN in the phone as well).

[Q] What US Carrier is the International GTab 7.0 plus (P6200) fully compatible with?

Sorry for what is probably a stupid question.
I am thinking of buying an International version of the 7.0 plus (P6200) but I'm having a hard time figuring out which US Carrier, if any, (AT&T, T-Moble or Verizon) is fully compatible with the table's supported frequencies.
Any help in pointing me to the carrier, that will allow the tablet to get 3g data and allow the tablet to make phone calls, would be greatly appreciated.
Also, if you are using a P6200 in the US, I would be interested in what carrier you use, your opinions of the carrier and your opinion of the tablet in general.
Thank you

Does no one know the answer or is the question so simple it is basic knowledge I should already know?
I'm not familar witht eh international model but I can tell you that it won't work with Sprint or Verizon as they are CDMA and not GSM. So that leaves T-Mobile and AT&T and it would depend upon what frequency the GTab7+ recieves, is it tri-band (850, 1800, 1900) or just a single band? AT&T uses 850/1900 MHz and T-Moblile 1900 MHz for 3G service. I would assume that it would be tri-band as are so called "world phones".
TMo also requires UMTS1700.
So almost surely it will NOT get 3G service on TMo. That's why there is a special Tmo variant.
Don't know about AT&T
Thank you for your reply!
Here are the listed frequencies for the tablet
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
it appears that it supports all the frequencies for AT&T and T-Mobile. I guess my confusion is I can't tell if the tablet will support 3G or just 2G (wouldn't be worth it if all I could get is 2G).

Ahh, that is what I was looking for. As much as I dislike them, seems I will need to go with AT&T if I get this tablet.
Thank you very much, both of you!
Sorry I got a little confused between tabs and phones. Verizon uses EV-DO (CDMA based) for 3G and AT&T is HSDPA (GSM based) at 1900 MHz. T-Mobile uses 1700 and 2100 MHz for 3G.
warning, if you plan on using as phone and tab, at&t may want to make sure you are on tab data plan as well an it could be pricey for both.
with that being said Im using this on att with voice and unlimited grandfathered smartphone data. havent heard a word from them. I pray it stays this way. I will fight them for it.
conclusion: best mobile device in the world right now IMHO, until 7.7 comes out.
P6200 and iPhone SIM
Hi all,
just to make sure...
If I get the P6200, can I just pop my iPhone 3gs SIM with unlimited data plan (as long as I don't use it too much)?
I saw someone said they can do that on the 7.7 thread but I wanted to make sure the AT&T iPhone SIM isn't restricted to iPhones somehow.
Thanks

I have GT-P620900 from the Philippines and I am my tablet in the US now. I tested using at&t sim card and it works when I tried making a call using sim card (gsm).

Hi Neogrin,
With the posted frequencies:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
it will work perfectly for 3G (HSDPA/HSPA+) speeds only on AT&T. You should get 2-4 Mbps downlink, or maybe even more with a good signal on AT&T.
Unfortunately for T-Mobile (whom I also prefer over AT&T), it will only work on their 2G network, at EDGE speeds, which would be about 200 Kbps if you are lucky. Actually, EDGE speeds are good enough for twitter, facebook, and a bit of surfing, but would be frustratingly slow for YouTube or downloading apps.
The Tab 7plus will NOT work on Sprint or Verizon as their CDMA, LTE, and WiMax networks are different technology from GSM and HSDPA and thus not compatible.
Internationally, the 7plus should work on almost any 2G or 3G network, with maybe a few country exceptions here and there.
BTW if you decide to activate your 7plus on AT&T, I can share a bit of experience. I received a Tab 7.7 3G this week, with a similar frequency list to the 7plus. (Unfortunately, it also lacks the "AWS" 1700/2100 band for T-Mobile). I went to an AT&T store today to activate the 7.7 on a month-to-month data plan, of US$25 for 2GB with US$10 per each 1GB of overage. They were not able to assign the data plan in their system to me, because the 7.7 3G is not an AT&T device. The same will be true for your 7plus. What they did to get it to work was to take the IMEI number from one of the other tablets they had on display in the store - making sure it was an HSDPA tablet, and not an LTE one - and used that to activate my account. It took them a while to figure this out, but when they did, it worked. Once the account was activated, and the SIM card was in my 7.7, it found AT&T service and I immediately got a welcome text message. However, data did not yet work - for that I had to do one more thing, which the staff did not know about (but luckily I did).
Go into Settings->Wireless and Networks->Mobile Network Settings
In there is an "Access Point Names" item.
Click on this, and you should see some entries. If it's a new AT&T SIM, it likely says "Cingular 410" or "wap.cingular" or something. This would be correct for a phone, but does not work with tablet data plans, so we need to add the correct one.
Bring up the menu, and there should be a "New APN" option. Select this. In the form which comes up, in the "Name" field, enter "broadband" (one word, no caps, without the quotes). In the "APN" field, do the same - "broadband" one word, no caps, no quotes.
Once you've done this, hit the menu again, and there should be a "Save" option. Choose this, and it will take you back to the list of APNs. Now in the list there should be an APN item called "broadband" which you just created. Press the radio button to the far right of the broadband item. It should turn green.
Give the tablet a few seconds, or a minute, and data should start working!
Hope this helps.

[Q] How to get 3G/4G with unlocked Blaze on AT&T

I bought one of these phones, rooted it, unlocked it, and installed CM9. I love the phone and OS, but I cannot get the 3G/4G to work on AT&T. Any ideas?
Yeah. The data network is incompatible. Different frequency.
Sent from my SGH-T769 using xda premium
Yeah I think all you can get is 2G (edge) on AT&T with the blaze.
I can say from first hand experience that the blaze works great with AT&T's 3g service. I bought this phone last week, unlocked it, and swapped in the sim from my old Aria and have been using it with CM10 ever since. Data speeds are around 3 to 6 Mb/s down and 1 Mb/s up, and voice and text messaging works fine.
For a more technical answer, AT&T uses the 850 mhz and 1900 mhz frequencies for UMTS (3g), and T-mobile uses 1700 mhz and 2100 mhz frequencies. The blaze supports UMTS on all of these frequencies so there are no technical roadblocks to using this phone with AT&T. http://www.phonearena.com/phones/Samsung-Galaxy-S-Blaze-4G_id6824
As for your problem of not getting 3g working, I had similar issues when first switching the sim card (especially on the stock rom). Check that your APN matches the one your old phone was using. On the stock rom, the phone did not auto detect the correct APN and this caused the 3g to not work. CM10 detected the correct APN right away though. Also, try turning data off and on or even rebooting the phone once you've checked your network settings.
I sold my other phone and no longer have it. Please confirm your APN settings, and how do I change them?
The blaze has all the frequencies necessary for it to do HSPA (3G/4G) on AT&T's networks.
You'll likely want to change the APN. On CM9/10, go to Settings -> Wireless & Networks + More... -> Mobile Network Settings -> Access Point Names.
I was careful in selecting this specific phone because of its compatibility with AT&T HSPA bands. I have tried the suggested tweaks to the APN settings within both CM9 and CM10, but I still get no visual notification that the phone is operating in 3G or 4G mode. The areas in which I have used the phone consistently provided 3G and/or 4G coverage consistently with my prior BlackBerry 9860.
Any additional tips/tricks would certainly be appreciated. I know this phone is capable of so much more than it's providing me at this point.

have you tried running a speed test to see if maybe it's just that the icon isn't coming up?
That is why it was called the "Merger Proof Phone"

Nexus 5 on Sprint Network

Can someone confirm if you could receive a Spark signal from Sprint? I am in Chicago area under Spark coverage but my nexus 5 still running on 4G LTE band 25 even I set priority to band 41. I called Sprint and I was told that I need to wait for update from Google to be able to get Nexus 5 work with Sprint Spark. is it true while Sprint is selling Nexus 5 on their site? I am thinking about returning the phone back to Google.
I am in NYC which also has Spark and I don't get those speeds or bands either. I have enabled them in the phone but always connect to the stadard band.
From what I read about Spark, there is a "Spark" network icon similar to LTE on devices that support it when they are on Spark. So it looks like we will need an update for this to work even though we have enabled the bands. Sprint has said that the Nexus 5 and LG G2 will get the update for Spark in 2014, lets just hope they mean January....
Thanks. Will wait to have another try before leaving Sprint.I hope Sprint spark is faster than T-mobile HPSA+.
There is Sprint LTE in my area, but my Nexus will not connect.
However, if I enable LTE-Only mode via the dialer menu:
*#*#4636#*#*
Then it connects to LTE.
I believe this is related to the issue described here: http://s4gru.com/index.php?/blog/1/...-due-to-circuit-switched-fallback-technology/
The Nexus 5 only has a single shared LTE/CDMA radio... So if the Sprint LTE tower doesn't support the new CDMA fallback (or if it's not enabled) then your N5 will ignore the LTE signal.
So you can try forcing LTE to make sure it works, but doing so will cut off your SMS/MMS/Voice access.
At least until the fallback is working properly in your area.
It's two fold. The firmware on the LG G2 and Nexus 5 is incredibly picky if you do by chance get a B41 connection. If it even sniffs a B25 connection then you will absolutely not get the B41 even if it's stronger. On the other hand, if you do get a B41 connection you need to keep an active data session or it'll boot you off in a few seconds. There is also ==the eCSFB issues that affect all sprint spark devices.
The second thing is that the Clearwire network (aka spark network) is very unpredictable. Some sites that are confirmed and known to be live for Band 41 refuses to allow connections from cell devices but allows hotspots while others allow certain cell devices and some all devices. YMMV.

[Q] Can an unlocked Pantech Discover (AT&T brand) use 4G lte data on another service?

[Q] Can an unlocked Pantech Discover (AT&T brand) use 4G lte data on another service?
Can an unlocked Pantech Discover (AT&T brand) use 4G lte data on another service? I know it has the correct network ability (LTE 700 MHz Class 17 / 850 / 1700 / 1900 / 2100) to work at 4G lte speeds on AT&T network, but I want to know if it will work while unlocked on T Mobile (that has the same requirements). The network abilities are confirmed compatible, and is not the question, will it reach the same speed even though it is not made for the carrier (T mobile in this case). I would love to find out before I spend the money to buy it brand new and unlocked, only to see if it will work or not. And if not, I have wasted the money. I have heard that this will not work, or might now that things have changed (No real help, and makes my more cautious).
Reading everything on the internet I can find. So far I've found the conflicting answers that:
1) As long as it has the network ability, then yes.
2) No unlocked phone will reach above EDGE speeds on another carrier. (May by very outdated, but can't confirm)
3) That might not be correct, unlocked phones will not, normally, work correctly on other networks.
4) It works 100%
5) It can only reach 3G
After several calls I've found out:
1) T mobile says:
a) Should work.
b) No idea.
c) Since it has the network ability to use 4G lte with our network, it should, but I don't know.
2) Pantech
a) Just try it.
b) I think so, but I don't know.
3) AT&T (the phone is made for and sold by them)
a) Unlocking will not limit the phone.
Is "No unlocked phone will reach above EDGE speeds on another carrier" just a myth now since "Things has changed" (what ever that means)?

T-Mobile has different LTE speeds depending on the area you live. In southern California T-Mobile's LTE is a little faster than ATT. Since both are GSM you will definitely have 3G, if on that phone HSPA+, but not sure on LTE. I was thinking that ATT and TMobile had LTE on different frequencies as they do not use the same towers etc.

LG Phoenix 2 (K371) Network mode issue

Hello,
I've got a LG Phoenix 2(K371) phone that I bought from Bestbuy and unlocked through AT&T
The phone is supposed to support the UMTS B1(2100 Mhz) frequency (as stated in specs).
I'm in North Africa right now for a business trip and unfortunately I wasn't able to get any 3G data with the local carrier that uses the UMTS 2100 Mhz frequency, I'm stuck with only 2G while my other phone works just fine.
I tried to change my Network Mode from 4G to 3G but the Network mode menu is missing!!!!!!
My questions are:
1- Does the K371 really supports the UMTS 2100 Mhz frequency ?
2- How can I change my Network mode from 4G/Lte to 3g/WCDMA?
Thanks
Did you ever get this sorted out? I am in Germany and can only get 2G also.
Same here in the UK! Only 2G.
My understanding is that either the official specifications of the phone are wrong - it doesn't support the HSDPA frequency of 2100 MHz, or (most likely) this frequency is disabled in the phone software settings since [email protected] doesn't use this frequency in the US. In any case it is very frustrating: I bought this phone convinced it is going to work while I am travelling in Europe, but obviously it doesn't as 2G data connection is useless.
Same problem in SE Asia. Phone doesn't have the right LTE bands but HSPC should work. Only getting 2G. No option in the hidden menu to change the modem RAT settings that I can see. *#546368#*371#
Anyone have any luck using the k371 overseas?
Same here...
I tried every single method I know in hopes that I could root the phone, but no luck!!!
I believe at&t disabled the said frequencies....
Our only bet is a proper root, and a custom rom..
any update on no UMTS 2100Mhz?
any solutoion on this issue?
I have found a solution. I am using it outside the US. I contacted my cellular provider, gave them the phone name (LG K371) and they sent me a text message with automatic settings for their data network. As soon as I opened it, I got a message like "data settings have been updated" and now it works on 3G and 4G without any issues. You may also be able to find these data configuration settings on your cell service provider's web site.
Seriously???
Please let me know is it AIRTEL service? since i am from INDIA.
we have the same problem in 2 mobiles..
Hmmm
I tried of calling and received setting for MMS , GPRS, INERNET but still i m seeing 2G symbol as E - edge detection
Please help me
Hi this is sainath
am also facing same problem, any one got solutions
please give reply.

Sorry for a late reply, but here's the real scoop about the LG K371 (AT&T)
First, being a "cheap" LG phone, there are very few bands actually included, and they only cover the main (not all) AT&T US frequencies, therefore it's no surprise that doesn't work on all overseas carriers. Again, they are covering only major US bands, and despite what it shows on the box or specs it may not be always true. B1 (2,100Mhz) band has different sub-bands, therefore it doesn't mean that the US B1 will work on an overseas B1, let alone the air-interface (2G/3G/4G/LTE) may not all be supported even if this sub-band exists.
Second, being that it's an AT&T phone, they are knows to load firmware with major restrictions for band selection called RAT Restrictions, which cannot be undone unless you can reflash it with a non-customized firmware, but you can't do that either due to the locked bootloader. A better option is to always go with the un-customized or Tmobile K7/K8 because they always have a lot more bands enabled than the AT&T version. Better yet, go with a Samsung which have more bands even on the AT&T models.
Bottom line, "cheap" phones along with AT&T restrictions will not work everywhere, despite the specs, and there's nothing you can do about it.
And my favorite old adage is "You get what you pay for!" LOL
