I have an HTC One M8 from Verizon that is Global unlocked. I live in Costa Rica now and when I got it I used it with the cell network here using a prepaid SIM card. My phone has worked fine for the last ten months, during a recent trip to the US I had a Verizon SIM card in and it forced me to upgrade to 5.0.1 (or well it kept popping up a when are you going to update notification every few hours until I relented).
Now back in Costa Rica I can no longer connect to the data network. I have the same settings and have tried everything I can think of. I've tried using GSM, UMTS, Legacy 3GPP multimode, and Global mode. I can make calls and texts fine and have good signal, but I don't get the data emblem or a data connection now. I've tried countless reboots, switching in and out of airplane mode, checking my phone credit using the mmi code, etc.
I'd like to just rollback to the previous version if it's not possible to fix the issue. Any suggestions as to how to maybe fix this or roll back the OS?

My MyTouch 4G slide has been sitting for a month or two after previously working fine. Now it powers up however it can't get a signal with my T-mobile SIM (or my wife's). I'm concerned that somehow the radio might have gotten fried. So far I've reflashed it back to stock, unrooted, and hard reset it a few times, nothing has worked.
If I go into Wireless & Networks, drop down to Mobile Networks, Then Network Operators, and "Search Networks", it takes a few moments and finds AT&T & T-Mobile (I'm in an area where my devices normally get full T-Mobile service). However when I try to connect to T-Mobile, I get a message saying "Your SIM card does not allow a connection to this network". Same SIM works fine in a G2, connected to T-Mobile.
Anyone have a way to test the phone radio, or perhaps have an idea on what it's issue is?
I have had this exact problem, and attempted the same solutions, but without success. Was working fine, and then 1hr later quit working and was not able to repair even after return to stock/deroot, etc. Doing warranted return, and just got replacement phone by mail for swap out from t-mo.
am a little worried about reroot and rerom in case I have another problem.
My device is doing the same thing. Not sure when it started... I havent used the MT4GS in a few weeks, picked it up and reset it back to stock everything, and it's not getting any service from any of my SIM cards. I unlocked it a while ago to use on AT&T prepaid SIM, and not even that will work... Any advice would be helpful...

I've used Z-Device Test by Zausan Innovacion Tecnologica to test just about everything on my phone.
I'm having a similar issue on mine after trying jupoeanutbear and failing. I have signal but data craps out at random times now.

Long time lurker, first time post. I am running a stock OPO 64gb with stock CM 4.4.4 on USA T-Mobile with unlimited data + int'l data. *Short version, OPO not connecting to data /MMS international & USA.
While in USA/WA, my mobile data was working fine. I crossed the border to Canada and my phone connected to Canada Rogers, but I was not getting mobile data or MMS. Voice and text were working. After calling T-Mobile several times, they "reset" their network settings to remedy, but still no fix. I had friends w/ me on T-Mobile branded phones, they had LTE / 4G on Canada Rogers. Internet browser said: ERR INTERNET DISCONNECTED.
I crossed the border from CAN to USA/WA, and my phone was still connected to Canada Rogers. I reboot my phone, and I only get T-Mobile voice and text; no data and no MMS. Called T-Mo again, and no fix.
I return home, swap SIM card from OPO to Nexus 5, and voilà! Getting LTE and MMS. Swap SIM back, and OPO will not connect to Data or MMS. So the problem does not appear to be SIM related, but OPO related. I wonder if my Nexus 5 would've worked in CAN for data/mms.
*About two weeks ago, while in USA, my mobile data stopped working, I had to get a new SIM card, which solved the problem, but I can't do this all the time, or when Int'l.
My question: How do I get my OPO to work w/ mobile data and MMS w/o getting new sim? I'd like the OPO to work in CAN and USA since I will be traveling to CAN often. Thanks.
Have you checked to see if your APN is correct?

I git a new SIM at t-mobile and had the same problem, voice and SMS only.
I reset my APN settings to default, and data and mms are working again.
APN settings all looked same as before though. I had tried resetting the APN in Canada, but it hadn't worked, but I didn't have Canada APN settings though...
Solved for now. Thanks.
My new Honor 6 H60-L02 doesn't seem to have a data connection. The telephoning/messaging works well, but when I am out of wifi range, and want to use the internet, the message I get is 'no network connection'.
Any help appreciated.
Sorted!!
It was my sim card settings, OK now.
Which settings you mean? I've got the same problem on h06-l04 and did everything like deleting the APN, tested APNs from other providers etc. - nothing helped. The SIM shows h+ and h all the time, but when I try to open a site or try to update my apps over google play the connection works a few seconds up to a minute and then the connection got lost again. It never happened on my galaxy s2.
I used the APN settings on my sim card providers web site and they worked perfectly. If I am not in a wifi zone the phone switches to h+ and performs very well.

What model do u have? H01, H11 - won't support Euro 3G, thay are only for China. H02 and H12 - should work fine with 3g. H04 - Should work fine with 3g and 4g in your country.
Also please check if your carier provides 3g service.

3G/4G issue
I'm also having the same issue with my Honor 6+ which i bought last month from dubai. I'm trying to use data connection using 3G/4G in india as i'm residing in India, but even after following all the required settings that are provided by my service provider and the other trouble shooting steps i'm still no where. It always displays the 3G/4G icon at the top but never works. I doubt if it is something to do with the software/firmware version. Please suggest.
I'm also having the same issue with my Honor 6+ which i bought last month from Malaysia and using in Bangladesh. I tried airplane mode on and off, it shows 3G for few moment or minutes but then again it becomes edge mode. Please help me out from this problem.. thanks in advance..
I live in India and I bought my Honor six plus online from a local retailer, and my phone can only access 2G data (or EDGE, apparently ) which is too slow to support anything. At first, I thought it was a sim card issue but I tried using the same sim in someone else's phone and that person's phone had no such problem. Even my brother's Iphone faced nothing of the sort. Any one know how to fix this?
Check on the back of the phone for phone number. On my honor 6, on the back on the lower part are 2 lines with text. on the second line I have found my phone model: H60-L2, in my case. Then you can check with, for example, http://willmyphonework.net/ if your phone model will work in your country. I know for example that my phone model will not allow 4G in all European countries.
If you prove that your phone is working in your country than its a matter of settings. You can try:
- Place the sim card with a data plan on the main sim tray. Honor 6 not rooted and running stable ROM will allow data only on the first tray. In Settings -> Dual Card Sim Management you can see which card is in which tray. If necessary switch the sim cards into the other tray.
- Check your settings and here the most important one is the APN. Make sure that the settings of your operator are correctly set in order to have mobile connection.
Generally the 3G network should at least be recognized, so if your phone is not registering with a 3G network then either it is not hardware compatible or you have placed your SIM in the wrong tray. Most probably is the first option and what you can do is to change the phone...
Man...i was having the same problem...well just 2 mins back!??
I have marshmallow update...and wat my problem was that the apn was set, though correctly, but in upper amd lower case....
And it seems apns are case sensitive...so check it!
Honor 6x is my latest mobile, which i bought a week before, it's seems like the mobile having data connection problems. till i'm using 4G sims but i'm not getting at least 2g speed, most of the time i'm not getting internet connections. at the same time it's showing H and H+ symbols ...
if possible, someone pls help me here.
Hello Everyone,
Recently I came back from trip to USA. Everything was working fine, I used Wind's roaming in USA. Ever since I came back to Canada, my phone is struggling to connect to Wind Home network. It almost always connects to Wind Away (roaming) even when I'm in the coverage zone. I tried a new SIM card, factory reset, *#*#4636#*#* steps and I'm still stuck. Eventually it connects to Home network after 1 hr but when I lose the signals (subway tunnel, basement), the phone is back to Wind Away and stuck again.
I tried Koodo and Virgin mobile SIM on OPO and they work fine, however when I put my brother's Wind SIM (which was not used in USA at all), the phone doesn't connect to WIND Network. The same SIM on LG G2 locked on WIND works fine. The provider says that they have no issues from their side regarding the IMEI and all that.
Can someone please help me with this frustrating problem? I'm running CM12.1 (currently stock state) and International OPO. Thank you!
I have the exact problem on Wind with my oneplus one. Went to Lac la Biche for a few days and now I'm back in Edmonton it's stuck on wind away.
So I recently bought a Sprint HTC U11 off ebay, and at first it didn't work at all with my T-Mobile SIM, all it showed was a full strength signal with a capital R next to the signal bar. I called Sprint and they confirmed it's unlocked, although they said it may still be tied in some way to the original owners account, which could potentially cause problems.
I managed to get it working on LTE, by going into testing mode (*#*#4636#*#*) and setting the network to CDMA/LTE only, but with this setting I can only use Data, no Calls or Text. It is also has Sprint as the provider instead of T-Mobile, and I can't switch on VoLTE (greyed out in the Testing menu).
I tested it with some of the other settings, but anything that turns on GSM makes it glitch out, connect for only a few seconds to either T-Mobile or U.S Cellular (a provider I automatically roam on where I live), and then disconnect and refuse to reconnect to anything until I switch back to CDMA/LTE and reboot.
Is this a common problem with the Sprint version of this phone? Are there any fixes for it? The phone is currently not rooted or modified in any way, and is running Android 8.0, Software version 2.33.651.10.
Thanks for any help.
