No cellular data after TWRP restore - Nexus 6 Q&A, Help & Troubleshooting

I'm trying to restore a TWRP backup that I made right after unlocking and rooting on stock ROM. But whenever I restore and boot the device, I have no cellular data whatsoever. I'm on T-Mobile and I'm choosing the fast.t-mobile.com APN in Settings (already selected), which obviously worked when I made the backup. Why isn't it working now?
When I restore back to my current custom ROM on the same APN cellular data works fine again. What's going on? The only difference I see is that in Pure Shamu ROM the APN is named T-Mobile US LTE instead of T-Mobile GPRS on stock ROM. But the settings look the same?
Any help is appreciated.

Double check the T-Mobile LTE APN is correct, you need the one with the - in it.
I think it's here. If you are off even one character, no workie. Page down to Network section.

I had the SAME EXACT issue... and I found how to fix it.
When its not working, Go into data usage settings, overflow menu, cellular networks, then access point names - click on the T-movile GPRS (fast.t-mobile.com) and make sure APN protocol is IPv4 and APN roaming protocol is IPV4 also make sure Bearer is set to LTE.

Rogers (Canada) 3G Settings?

I'm having troubles connecting to 3G with my IS. Up until a few days ago I had an HTC Desire Z that was unlocked, and rooted. It worked great on rogers 3G.
I'm lost as what to try. I've accessed the *#*#4636#*#* menu, and tried GSM auto (PRL), and I end up getting 3G but then it drops. The only way I seem to be able to keep the data connection is to set it to GSM only which gives me 2G/edge
anyone know what else I can try?
Thanks
Have you added an APN for Rogers?

It's under Settings > Wireless & Networks > Mobile Networks > Access Point Names
I'm using a Bell Incredible S on Telus after entering the relevant Telus APN settings, and get the HSPA/3G icon.
well I got it working. When I checked the APN, the MMS proxy ip was missing. I did have it all in there correct before though. I guess from the *#*#4636#*#* menu switching settings in there trying to get it up deleted the proxy ip?
Either way, it's working great. Thanks for the reply thedosbox

[Q] No 3G with 2.3.3 Gingerbread?

I've just upgraded from 2.2, and now I can't seem to get 3G working with AT&T. Does anybody have any suggestions? I've tried fiddling with the Settings but nothing seems to work. Help is appreciated, thanks.
In the About Device, the Mobile network type listed is HSDPA, but the Mobile network state is Disconnected.
Have you checked your APN settings? Also what's your baseband version showing in 'About device'?
Please use WCDMA mode
Go to Settings, Wireless & Network, Mobile Networks, Access Point names and make sure you have one called Broadband (assuming you are on the ATT monthly data only plan)
If you dont, create a new APN and name it Broadband & make the APN Broadband as well. Just leave the other options and save it & select it.
I think by default it comes up with the ATT wap.cingular APN which doesnt work with the Tab Data plan.
Flash the bell modem then set the apn to get data and phone working after flashing stock 2.3.3?

Thank you so much! This worked! Just did this and restarted.

no 3G after flash

so i got my tablet back up and running, but its not showing any signs of Cellular life
i flashed CWM7 and i have it up and functioning. i have the stock AT&T modem from the [MODEMS] list, should i apply a different one?
i have the APN settings correct, however, i'm not sure why the tab isnt registering on the network?
i just wanted to post a quick update on this.
i did have wrong APN settings :/ i was using a APN for a phone vs just mobile broadband data.

Throttled LTE? Way to force HSPA+(regain 3G after throttle) to conserve battery

Pulled from the Inspire forums and can confirm working mod.
PROCEDURE FOR ROMS WITH A SINGLE LOCKED APN:
If your APN is locked (it shows the lock symbol and you cannot change the settings), then we're just going to add a second one.
From the APN screen, press Menu>>New APN. Here are the settings for your 2nd APN. Everything is case sensitive and must be entered exactly as below.
Name: Media Net (if your 1st locked APN is named Media Net, then just name this one Media Net2 - this name in this field isn't important as long as it's unique)
APN: Phone
MMS protocol: WAP 2.0 (this option might not be in your APN, so don't worry if you don't see it)
MCC: xxx (Don't change this number)
MNC: xxx (Don't change this number)
APN type: default,admin,hipri (notice there are no spaces between the words and the commas)
APN protocol (if applicable): IPv4
Everything else: <Not set>
Once you have the above settings entered, press menu and save. You will exit back out to the APN selection screen. Now you need to select the little round button for the new APN (Media Net/Phone) that you just created. Your phone's data connection will drop for several seconds as it switches to the new APN, and then come back. If you find that your connection doesn't "stick" on the 2nd APN (i.e. the selection button keeps reverting back to the 1st APN) then reboot your phone and try selecting the 2nd APN again.[/COLOR][/B] It is mandatory that the 2nd APN is selected in order for the speed benefit.
We're done. If something went wrong and you need to revert back to your default APN config, from the APN selection screen just press menu and select "Reset to default".
Will this allow tethering without the tethering plan?

Correct. I am on a $30 Unlimited LTE data plan no tethering but have it enabled with this mod.

Awesome!! Thanks!!
Even better it drops us off of LTE, i.e. we can now turn the darn thing off and save some battery
This doesnt let you use LTE 4g while doing tetherning. After adding this apn it kicks you to the HSPA+ 4g.
But this is an easy way to create an easy way to switch between LTE and HSPA+
Edit: also it didnt allow me to do tethering. Said i had to dial 611 and get it added.
I seem to be doing something wrong... I made the second APN and activated it. When I try to use the WiFi Hotspot App, I get a message about adding tethering. Should I be using a different app?

This may be but my internet icon has not changed. Showing 4G but that is probably due to the market I am in is not an LTE market.

Yea when you are on the 4g LTE network, there is a little LTE underneath the 4g symbol

Have you followed step by step? Yes? Then have you tried rebooting the phone?
Is there any way you can update that APN to work with LTE 4g.

Sorry as of now I don't have a way. Will be figuring that out shortly.
Does not work for me.
Followed steps and reboot. No good.
Not Working
It works for a second and then it reverts back to that you need a tethering plan. Any other info. Thanks

I've ran it for about 2 gigs today and had no issues. Also once you turn it off the next time you wanna do it you will have to switch back to the stock APN and then back to the one you made. It's not perfect but it's better than nothing right now.
I didn't use these settings to enable tethering, but I entered them just to get ANY sort of data connection. It definitely solved my issues. Thanks a lot!
Won't revert to default
I set up an apn for hspa+ before I could get a 4g sim. I've switched sims and now I wanted to go back to default and it said I had no data due to an apn error. The radial box is selected for the original apn.
It would work for a second and my laptop would see the network but quickly went back to telling me to go to AT&T and get a tethering plan. However Having the second APN seems to help when the data gets flaky, which is VERY often. Speeds are erratic and I often can't get ANY data.

would love to see this work with the LTE connection.

[Q] Switched to T-Mobile, No MMS over Wifi

Hello,
Normally I can find everything I've ever needed by searching here, but I was not able to find a solution to this one.
I just switched to T-Mobile from AT&T, and brought over my SM-G900A.
When I put the SIM in at first, I got voice and SMS, but no data. I looked up APN settings, and created a fast.t-mobile.com APN using the recommended settings, except for APN protocol. Data now works, but still no MMS unless I disconnect from WiFI
MMSC is set to http : //mms.msg.eng.t-mobile.com/mms/wapenc (no spaces)
APN Protocol is set to IPv4 (This is greyed out and cannot be changed to IPv6)
However, MMS only works when connected to data only, not WiFi. I cannot seem to find a way to make this work when connected to WiFi, which I would like to be able to do. Any ideas?
My thought is this might be related to WiFi calling being a native feature on T-Mo devices but not on AT&T. Thoughts?
Thanks guys!

My thinking is , is thats an internal thing with att software in the s5. Just because u switched to tmobile wont chang the software on the phone to tmobile even ur software updates to the phone will come from att not tmobile. I always have to have data on to send mms. I could be wrong but i think thats whats going on

You can achieve WiFi calling and Texting which will send MMS over WiFi by installing the alliance ROM. You first have to be on KitKat 4.4.4. After thay flash the ND3 kernal and install root via towel root, next install safstrap and flash alliance ROM and bam you should have WiFi calling and texting enabled. I am currently on the at&t s5 using T-Mobile.
I may have the links on my laptop if you need them. Just let me know.
