[Q] Razr HD XT925 not connecting to LTE

I just bought a Fido Razr HD for connecting to Rogers network. To my surprise, I was able to connect to Rogers even though it is a Fido phone. Never the less, I paid and got the phone sim unlocked. But I noticed that my Razr never connect to LTE. It always shows it connected as H+, which I assume to be the HSPA+ network. I verfied the following:
-Rogers LTE APN for mobile - checked this against entries posted here on XDA for Rogers
-Network select set to GSM/HSPA/LTE (Auto)
I do get a strange error every time i change from another sim back to my Rogers's one, it says something like no suitable network -15, something like that. I assume my problem has to do with it being a Fido rom working on Rogers.
Am I missing something really obvious?
Thanks,

Have you tried configuring phone according to SIM?.. Configuring it according to sim will load Rogers ROM on it and it will install all Rogers crapware along on it. But i think if you don't see the LTE , it is worth trying. Also make sure your area have LTE coverage.

Yes I have already converted to crap Rogers bloatware rom. It does that automatically when you put in a Rogers sim. Now I got bloatware and still no LTE. My Rogers work iPhone is happily LTE'ing at like 20 mbps, this one is only doing 5 mbps, booo.

hmmm.. okay.. do one thing.. Go to setting and then mobile networks and Select network.. make sure GSM/HSPA/LTE (Auto Mode) is selected. Secondly, Remove the sim and restart the phone and then re-insert the sim and see if it works. If still it don't. Simplay factory reset it and check.

Just here to share my experience because I had a similar problem too.
I'm with fido carrier and got the razr hd with fido (in futureshop) which sucks.
Anyways long story short, same thing happened to me it kept on staying on H+ which I did speed test is only around 2-5 average...mostly 2max.
So I went in LOTS troubles finding out what's wrong and GUESS WHAT when I get the phone and the micro sim card with the sales HE SAID it IS LTE supported (because there are two different micro sim cards....one supports LTE and one doesn't)
Then I went through all troubles and finally had to talk to on of the representatives ONLINE and tell them to send me a LTE micro sim card.
For my fido sim card it does say LTE on it but don't trust the people you call you gotta force them to send you an LTE micro sim card because I called LOTS times to fido and some say on there should be LTE labelled on the micro sim and some say don't know and some say it shouldn't which pisses me off a lot until I did the ONLINE chat and they finally send me the LTE micro sim card and it works....
But one thing is don't expect to have LTE everywhere in Vancouver because as for now, I know I get LTE more in burnaby like near metro (but not in metro hahah...sometimes not always) and not a lot places in Richmond as for downtown not too sure because I went there 2-3 times only got H+ but I don't go there often.
At least i know LTE works which is the main point so I guess after all you have done, make make make sure your micro sim is LTE compatible.
P.S. for fido the LTE is included when I sign the contract so no charge to me for them to send me one but I'm not sure about rogers.
Hope this helps more or less.

Hey everyone, thanks for all the responses. Just prior to reading this thread, i came to the same conclusion that this is sim related as I put my micro sim into my girlfriend's LTE phone, it can only go up to HSPAP. I realized that it must be sim based. I was cheap and just cut down my old sim, i assume my old one did not support LTE on Rogers. And with this response I am 80% sure this is the problem. I will go pay 10 buck and enjoy blazing LTE tomorrow!!!
Thanks all!!

Oh they just letting you know....which I didn't say because it was a super long story that's why I briefly said it....somehow DO check if your rogers micro sim card says LTE or not on it because what I left out and didn't easy earlier was that I went to buy a micro sim card at the store and I asked for micro sim card...and at last they still only give me a regular micro sim card that's why I kept on confused if it does say LTE on it and went online chat to complain what happened. So double triple make sure or if you know someone in rogers store then it'll be good too. Because after I got the fake LTE they kept on saying on maybe because the tower delay wait for a day or two some said and some said few hours but guess what! when fido mailed me the LTE card the LTE works RIGHT AWAY....so ya...find a way to make sure the card is LTE micro.

THE AT&T DATA THREAD: The Answer to getting LTE working on your N5

IF YOU HAVE ACCESS TO LTE ON AN AT&T PHONE, YOU DONT HAVE TO DO ANYTHING!!!!!!!!
IF YOU ALREADY HAVE A SIM CARD THAT WILL FIT IN THE N5, YOUR SIM IS LTE CAPABLE AND ALL YOU HAVE TO DO IS GET THE RIGHT DATA PROVISION. YOU DO NOT NEED TO GET A NEW SIM!!!!!!!
This happened when the N4 came out and I came to the rescue far too many times to count...and I've already started to read threads about it so here we go!
You just bought an N5 and are either worried about getting LTE or can't get LTE connectivity on your N5. It's a really big issue with a really simple solution. You need to make sure of a few things.
1. You have a SIM that can receive LTE frequency
2. Your data plan is a LTE provisioned plan
3. Your APNs include an LTE ANP
1 & 2 can be solved at the same time and 3 should solve itself in most cases.
Here's the big issue: AT&T doesn't have a data provision for the N5 (or the N4). Your customer service rep will take the IMEI number from your phone when you ask for a new SIM and it will come back with their basic GSM plan by default. This caused awful data speeds on the N4 and will disallow LTE on the N5 so you need to inform them that this will happen before they go through the process. A nice rep will understand. An unknowledgeable rep will claim there is nothing they can do. Ask to speak to the manager. If none of them can help, take your new LTE capable SIM and walk away.
Now after you leave the store call up customer service and tell them you just got a new *insert LTE capable AT&T device here* and you can't find the IMEI number. Tell them you tried to go into the store and they were unhelpful so you're calling. The person will immediately become helpful and generate an IMEI number. They will provision your data using said serial number and you'll be good to go.
BEFORE inserting your SIM, start up your N5. Go through the setup process that you have to go through and then turn it back off. Plug in your SIM and reboot.
Go to Settings > Wireless & Networks > more > Mobile Networks > Access point Names. In there you should see an AT&T LTE APN and it should be already selected. If not, select it. This should be all you need to do. It really is that simple.
NOTES:
- All SIMs that fit in the N4 and N5 are LTE capable
- Here is what your AT&T APN should look like
- If you have any issues, post and I'll do my best to help
As always, Thanks are appreciated.

So even if the rep in store "can't help" I'll still walk out with the SIM card I need? Also, If I don't have my N5/IMEI in hand when I go in can I still setup a plan and get a SIM card? Thanks for the post!
EDIT: Going in with no phone I don't know rather to tell them I have a N5 coming or try to find a friends that will give me their IMEI that I can give them...

You'll get a SIM card no matter what because those are free...it just won't be provisioned properly unless you get a knowledgeable rep.
Having an IMEI in hand makes life easier; having your N5 will make it way easier. The SIM needs to be activated in the store and they will need an IMEI to activate. Just wait till you get your N5 to go through all this. It won't do anything to help you until you get it.
The IMEI will be on the SIM tray!

Ok, I will wait until Wednesday to go in then...one last thing, if it gets to the point I have to call ATT, when I say I can't find the IMEI won't they just tell me to flip the phone over or look in the settings, etc.. instead of generating one?

No.
They will ask you if there is a barcode / serial thing on the back of your device. You say no. Boom, done.
edit: don't forget to hit the thanks button!

So just going in and asking to exchange your sim for a micro sim isn't enough?

I have a note 3 right now with 4g. I was going to use the same Sim card in the note and put in the N5. Should it work out of the box or do I still have to take it in the store? How will I know that I have a an imei card?

Do you have a SIM that will fit in the N5? If not, follow my steps. If so, skip ahead to calling AT&T customer support because ALL MICRO SIMS ARE LTE CAPABLE.
What do you mean by an IMEI card? All phones come with an IMEI.

great. AT&T why are you so terrible.

Im sim is in the note 3 rught now. Sending it back to att. Getting the n5 tomorrow. New to the Sim card thing. Coming from sprint. Just had to ask.

Hey guys I'm going to switching to straight talk att am I ordered the lte micro sim from them and plan to activate tomorrow should I expect to jump through hoops to get lte or expect the same issues as att users...not sure this is my first try at prepaid

same things will happen. You'll need to get an LTE data provision but will be unable to using your N5 IMEI

If you have 4g on your note 3 it means you already have a LTE data plan. All you need to do is take the sim out of your note 3 and pop it into your n5, no need to call anyone or make an unnecessary trip to the store.

4g =/= LTE in AT&Ts case. 4g can mean HSPA+ 4g!
If you have access to LTE currently YOU DO NOT NEED TO DO ANYTHING.

If you have a device and you can't find the IMEI, just go to the settings and about device to view it.. Wouldn't they ask you to do that?
Look, I know you want to dumb down stuff and give advise but some of it is just incorrect, not dumbed down.

Dial *#06# on any Android smartphone and it'll display the IMEI.

It's possible that the reps @ the AT&T Stores in different areas aren't properly keying the IMEI in properly. If at all possible have them SCAN the IMEI barcode on the back of the phone.
I went down to the AT&T store here locally (Bay Area, CA) and the only problem I had in the process was a 30 minute wait to see one of the reps.
I was previously on an unlimited data plan that I've had setup since I got my original iPhone 3G - 5 years ago. NOT an LTE plan by any stretch.
He went in the back and grabbed the sim and started the process of adding it to the account.
He scanned the sim and then scanned my phone -- It CORRECTLY recognized the device as a D820 **AND** automatically updated my data plan to the LTE Unlimited.
The only thing the rep had to do was press confirm a number of times. Not once did he have to manually adjust anything.
We waited about 5 minutes for the sim to activate, slipped it into my N5 and powered it up - Instant LTE service.
So AT&T *does* have the IMEI Registered for the N5 with a corresponding LTE Plan. If someone is trying to key it in and getting an error.. they're likely not typing something correctly.

I'm already using a note 3 on at&t with LTE already enabled on my plan. Also,my note 3 already uses a micro-SIM. I should be good to just swap my SIM into the n5 right? I have written down the default AT&T APN just in case it gets list on the n5.

Straight Talk AT&T Sim and LTE

I've read numerous threads here and elsewhere on the web saying that if you have an old Straight Talk AT&T sim card you have to buy a new one to get LTE to work with your Nexus 5. This was not the case for me so I thought I'd share. I ended up calling Straight Talk to ask them about it and after waiting on the phone for 30-40 minutes they said they "enabled" LTE on my account. They then gave me the following APN settings to use:
Name: Straight Talk (can be whatever you want)
APN: tfdata
Port: 80
MMSC: http: //mms-tf.net (no space after http:, had to add one because I can't post links)
MMS Proxy: mms3.tracfone.com
MMS Port: 80
Keep in mind, the APN type is not set. I was skeptical that they had done anything at first because after using the seemingly lackluster APN settings they gave me I still wasn't connecting to the LTE network. However, after waiting a bit (maybe 30 minutes or so) my phone started connecting to the LTE network. The only thing I cannot get to work so far is receiving MMS messages. Also, it's worth noting that the Straight Talk person I spoke to didn't really sound like they knew what they were doing, so I feel like I kind of lucked out with this one.
************************* EDIT/UPDATE *************************
So my billing cycle finally started again since the above happened. It seems that whatever Straight Talk changed with my account from when I talked to them has been reset. With the above settings I no longer get a data connection at all and after my phone is on for so long it will just stop connecting to any cellular service at all. I changed my APN settings to what they were previously and my phone started to work again. This is beyond frustrating - I'm giving up on the old AT&T sim card and will try a new one as most other people have suggested. The APN settings for old Straight Talk AT&T sim cards if anyone needs it:
APN: att.mvno
MMSC: http: //mmsc.cingular.com (no space after http
MMS proxy: 66.209.11.33
MMS port: 80
APN type: default,supl,mms,hipri

I've tried using these APN settings to no avail and had to revert to the old settings. Lately my signal constantly bounces between 3g and H(not H+). I'm wondering if I should see if this is possible and a solution for me.

Here is the solution for me. I have a Optimus G Pro. Was on ATT gophone SIM for about 6 months. LTE worked fine. Switched to Straight talk SIM and only got HSPA. Called Straight talk because I read somewhere that they had to activate the LTE on your account. Was on the phone with 3 different people for an hour. They asked what kind of phone did I have and my zip code. Then they had me go through my APN settings. All was fine. Then she said that LTE is not available in my area. I said BS. She said please refrain from using the B word. I said huh? The B word. Oh. The word BULL? she said yes. haha. Anyway I had ordered 2 SIMs from the website for $6.99 with free fedex shipping earlier. I needed an airtime card so I went to Walmart and saw the activation kits that includes airtime cards. So I got that. It has an activation code in the package for CDMA phones and came with 4 SIM cards. A nano ATT and a nano T-mobile for iphone. Also came with a full size card for ATT and one for Tmobile. The cards could also be punched out to make them a micro SIM. First of all the SIMs were in the wrong slots in the package. I was a little confused at first but then I figured out what the did. Here is the key: the SIM card that I ordered from the website has a model number of: TF64PSIMC4MB. The one that came in the activation package model number is: TF64PSIMC4BMB. Notice the "B" before the last MB. I called Straight Talk and used their automated system to switch SIM cards on my account and about 10 minutes later the new SIM starting working with LTE. I verified this earlier in the day with a friend of mines SIM card. He had the one without the B. I swapped out SIMs and he no longer got LTE and I did with his SIM. So... Make sure you get the SIM without the B.
On a side note: I was getting anywhere from 12 to 48 Mbps on GoPhone. I just now ran a speedtest and got 12 Mbps on Straight talk. I will run some more tests at different times and different locations and report back if anyone is interested.

His bootloader is locked. He got an straight talk activation kit from walmart and has the verizon-straight talk sim card into the phone. He has no mobile data but can still get regular phone signal. Can someone tell me how to completely flash the phone to straight talk from verizon?

Could you guys , anyone, tell me if you can roam on regional towers like verizon does with straight talk smart phones? I've tried selectel in the past and have had nothing but trouble thus far.
I tried activating an old droid x2 on tracfone and when I got it home it wouldn't roam on regoinal towers where verizon and tracfone dumb or feature phones will roam. I was told that tracfone android phones will only operate on verizon towers only. Since I had verizon before, and the tracfone coverage map covers my area, I assumed it would work. After a lot of back and forth travelling 45 min one way to activate on a verizon tower, and it finally did, I had zero coverage once I got about 30 minutes from home and then again none at home either. A tracfone rep as well as other forums said that tracfone androids only operate on real verizon towers, and at my home there's only regional towers.
So does anyone know if straight talk will roam on towers that verizon normally does? I know selectel did without data, voice only, at home on those regional towers, then something screwed up and it now only works on verizon towers or verizon network extenders which I don't own. Since selectel released their 4g sims, my selectel dealer said that would fix it. But no it didn't . I've been unable to get a straight answer from either selectel or the selectel dealer in my area, he originally flashed it to 3g only which he guaranteed me ws not illegal, but I wonder about that. Anyway, They can't get it fixed back properly.
If I can get a straight talk monthly plan cheap enough, I'd gladly switch as long as it roams on regional cdma towers that I have both voice and data on with verizon.
I just can't afford big red anymore, at the moment.
Thanks for any and all responses.

Nope - Straight Talk doesn't do roaming. You pay less, you get less... Don't expect ST to do OTA updates either - they won't!

No need for any OTA updates really. As a former VZW user I found out early to never take an ota from big red

Verizon S7 Edge (SM-G935V) on AT&T with LTE tip

Hi all, just giving a quick 2 cents after my recent experience attempting to activate a Verizon S7 Edge on AT&T.
*Following a data reset you will need wifi for initial setup if you are using an AT&T sim card.
After following the guide in AT&T's web site for APN settings I was not able to get any data or mms service (this is using the NXTGENPHONE APN), so I did some experimenting. The following APN settings worked for HSPA+ data and mms, but NO LTE and NO MMS if connected to WIFI:
Name: ATT
APN: phone
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://mmsc.mobile.att.net
Multimedia message proxy: proxy.mobile.att.net
Multimedia message port: 80
MCC: 310
MNC: 410
Authentication type: not set
APN type: default,mms,supl,hipri
APN Protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Bearer: unspecified
Mobile virtual network operator type: none
Mobile virtual network operator value: not set
So at this point I had NO LTE service and NO MMS IF connected to wifi. Utilizing the LTE Discovery app from the play store I could see that LTE was "not available" but on my wife's S7 she was getting LTE on Band 4. To make a long story short I got online to an AT&T chat rep who told me that HSPA+ and LTE are the exact same and they just show up different on different phones... THIS IS NOT CORRECT!
I educated the dumba$$ rep that HSPA+ and LTE are not the same, and asked to speak to a tech support SPECIALIST. After a short wait for transfer the final solution that worked was to have the specialist change the IMEI on file for my phone number to an AT&T branded Note 5 (I had an old one on the account and just used that). I then restarted the phone and had to wait about 10 minutes for the HSPA+ to change to 4GLTE signal. MMS now works when connected to wifi as well! Please note that this was achieved using the above mentioned APN settings- using AT&T's guide for NXTGENPHONE still results in NO data or MMS.
So the bottom line when transferring a Verizon S7 Edge to AT&T:
1. Use the above APN settings
2. Call AT&T and change your phone number's IMEI in their system to an LTE capable AT&T branded device (in my case note 5 worked)
3. Reboot and wait about 10 minutes for the signal to register
**DON'T let a representative tell you that HSPA+ and LTE are the same thing.. we're talking 8 Mbps vs 50+ Mbps download and 2 Mbps vs 20+ Mbps upload!
Cheers

Did you by chance even try the U firmware? It should work on any US carrier since its the firmware on the US Unlocked S7E and should have necessary files

you just flash the odin tar then root as usual.. the U firmware is for the US unlcked

I flashed first the 935U firmware and then activated the phone with AT&T, once you insert the sim the phone reboots, changes the APN while it reboots and once it finished all data/talk/text services with AT&T are fully functional. I am guessing Verizon lokcs down the APN features of the 935V firmware so that we stay with verizon.

I'm planning on flashing that rom tomorrow. The issue I have is modifying it for unlimited tethering as I use MetroPCS and pay for unlimited Internet. Fox fi does work but counts against my hotspot data. I tried it with a vpn but I use my hotspot for Netflix and I get an error saying to disable the proxy service or vpn. Wifi tether router connects but I get no Internet. I guess the main issue for me is getting the damn netflix to stream off my hotspot via chrome cast. I'm all ears, open to suggestions and help. Ps. I am currently rooted on Verizon rom. All apps are also paid apps not trying to free load here as I believe hard work should be compensated for. I also would love to have the video calling and wifi calling that I pay for.

My brother actually tried this. I sent him my 935V after I flashed it to the 935U firmware. He had the same problems the OP had where MMS and data won't work unless it's on the HSPA+ APN settings. He's coming to visit soon so I will try going to a store and seeing if they can set it up with a new sim. Or should I just call them and have them switch the imei?
Not sure which route is better here.

I actually just flashed the U firmware and now am right back where I started. Could be that for my region att has a hard time registering it. I'll be calling att this week and will post back my findings. I do like the U firmware better though. Seems cleaner and faster.

I think AT&T just block LTE access for non branded devices. Since you mentioned that it works after you register the sim with your AT&T note 5.

I just did a massive conversion of our squad car laptops for law enforcement at work from VZW to AT&T. The way they provision LTE access is trying the ICCID (SIM Card #) to the IMEID of the devices GOBI modem. All of my rigs came up on HSPA+ and not LTE. Once I sent the ICCID and IMEI of the particular unit to our government rep the mobile came up on LTE. I'd try calling them and saying you need LTE provisioned on your SIM. Provide the ICCID of your SIM, the IMEI of your device and your mobile phone #. Hope this helps.

I tried this with my brother's phone and they said that because it's a non at&t branded device there were limitations on what may or may not work when it comes to data or messaging because they don't guarantee anything as it's not theirs. So he had HSPA+ speeds for a few days until i saw this thread and called again. I gave them the IMEI from a display phone and it worked fine after that.

Thanks, he didn't really care as he's just happy with the phone but I'm glad I got it working as it was intended. By any means necessary.

After flashing the u firmware I called att and was able to get it activated again. Just takes persistence and patience lol.

Glad to hear it worked. I remember when I had a Nexus on AT&T, and I had to call them to have LTE work using a different phones info lol.

Does anyone have any experience with Cricket? I'm thinking about using my S7 Edge on the U firmware with Cricket, but I know they don't have the same level or type of customer service as AT&T. I'm hoping it will "just work", but it sounds like it might not.

Hi Geoff,
Don't know if you're still considering using a Verizon S7 edge on Cricket. I currently have one and it works fine with the network. And I have no issues with calls or MMS via LTE. You only lose connection go Band 17.
