Could be alot off things. A issue with the sim card to not being carrier permited. Could also have being blacklisted by a carrier .
bought a new sim card no dice....also the phone worked prior to this for like a month how would it get black listed....this happened immediatley after i hit gsm only by accident in phone settings
I have a solution!
Edit: I noticed you started at least three separate threads with different bits of information... Not very good forum etiquette.
I haven't spent time to research this, does your MTS SIM card allow 2G roaming on Rogers? Or only 3G?
I can reproduce the problem, I am running CM7 on a 9020A, with the XXKB3 radio, on the Bell/Telus joint HSPA network, which does not have a 2G GSM network.
On the 9020A: toggling 3G back on, then reflashing an appropriate UCKB2 or UCKD1 radio should fix this. (Either through fastboot or with CWM and the appropriate zip radio files.) You can then reflash the 9020T uncapped XXKB1, XXKB3 or XXKD1 radios afterwards if you wish.
Hope the above helped,
Darkshado
ok im on the same model but in manitoba on mts ill try these radios tho thanks for the input ill let u know how it went
well i just tried uckd1 and nothing...about to try uckb2
attempted to write uckb2 but it said failed and i don't wanna try that again i briked a phone like that once.... so still emergency only calls and im on uckd1
ok! we have progress but not all the way there yet...i can now find the MTS network with uckd1 but when i click on it...it says unable to conect at this time....when i hit select automatically it says registered on network. This has not fixxed the problem just yet tho...any other suggestions?
yes my bad about multiple threads....anyone have the unable to connect problem before?

[Q] HTC Sensation no signal (no service) issue

Hi ,
i am facing no service issue with HTC sensation xe with audio beats i have tried custom roms and stock roms with no luck , did factory restore , i have s-off +root.
hboot version is 1.27
baseband : 11.76A.3504.00U_24A.3504.31_M
When i turn on the device without sim card it says "Please insert sim card" and when i put sim card it says limited service and no signal with cross on signal bar .
Please tell me what should i do to fix this issue also what do you think its a hardware related issue ?
One more thing .. when i insert the sim it pops up the available networks and when i try to register on network it says Your Sim card does not allow to connect this network.
Also when i put the phone in air plane mode i can change the network mode to GSM only and WCDMA but when airplane mode is off and radio is on i can't change those settings .
if i go to testing section by pressing *#*#4636#*#* and then i go to Phone settings i see there "WCDMA preffered" as the network mode and when i try to change it from dropdown list it doesn't allow me to change .
do you think if i flash some other radio/rom it will work ?
also what other thing can i do to figure out the issue .
Thanks Much .

Hi,
It seems that your radio and firmware should work for most ROMS around.
How old is your sim card?
It might be worth trying to get a new one.

No .. Sim card reader is also fine because i can still see the sim toolkit folder and when i put the sim in device it shows me a popup to select network when i try to join it fails to register on network .
also i can dial emergency numbers.
i don't think the sim card reader is broken . phone is detecting the sim but no signal .
if there is a problem with signal IC then it should not detect any network operator to choose from .. so it seems its not a hardware issue
Thanks

Hi, have you managed to fix this issue? I have exactly the same problem with a 3 week old phone!
I called HTC to let them know and they think it is a sim problem, however, my sim is very new and is working in other phones!
I don't know what to do, I needed a new phone for school and to my dismay, it is not working!!
It was working until last week and I haven't damaged the phone at all, I am very protective over it!!!
I have read stories over flashing the phone, but I worry that I will damage it if I do so, and my parents just spent a lot of money on it for me. LOL!
My sisters' and I all got the same phone, but theirs' working fine!
Please let me know if you can help me
Thank you

type in dialer *#*#4636#*#* and go to phone info
from there it has options for network
I seem to have the exact same problem as described above (no signal, sim card seems to be fine)
Did any of you fix this?
Had same problem on nexus s after updating from jb to ics,no signal problem...changed sim card,everything fine..

HTC Sensation T-Mobile 4G
I think I had the same issue (as described here). While I'm not really sure which of all the tricks tried that made it work, I'd recommend trying yet another SIM. Good luck!
Edit: After all, it doesn't look like it works. My current provider claims this HAS to be related to SIM-locking.
Edit #2: Check for IMEI blocking.

[Q] Unable to Register on any network Please help.

I just sold my i9003 to my friend. When he inserts his airtel sim or any other sim and give a network search and click on airtel (or corresponding network) he gets the error message 'Can't connect to this network right now. Try again later' several times in two days we have tried and still get the same error.
Ref: My original sim in the phone :Airtel
My rom : cm 10.1 alpha 9 (Dhiru)
I have tried reinstaling the Rom to no avail. Please note that this problem is only recent. I have been using this rom (cm10.1 a9) ever since its release with no issues, the issue occured only when I changed to a different sim. However, it still works on my sim.

So sorry I meant D821
have you tried to use a different sim card? someone elses sim card..
My nexus Sim is Vodafone and I have a tablet that supports calling with Etisalate Sim, I switched the Sims and the Vodafone one works perfectly on the tablet but the Etisalate don't work on the mobile and when I returned them back the Vodafone don't work again and the Etisalate works again so the problem is with the phone
I tried re flashing Paranoid Android but the same problem
Try flashing stock. If it's the same, it's hardware. Sim card, device or something. Or its carrier related issue.
Sounds like the radio is set to LTE only mode.
Dial *#*#4636#*#* and check your network configuration

Nexus 5 cellular network issue on 2G only

Hello everyone,
One month ago my device had a problem of rebooting again and again and again. . . , I give my mobile phone to service center, they said you need to change motherboard to solve rebooting problem.
But I didn't change mother board, my rebooting problem solved when I pressed power button hardly.
In service center they disassembled my phone to checkup. after then when I got my mobile phone back my new problem started.
My problem is with cellular network, my build number is MMB29K my radio is radio-hammerhead-m8974a-2.0.50.2.28 my device bootloader is unlocked. my bootloader is bootloader-hammerhead-hhz12k
My device is unable to find cellular network when I set preferred network type to 2G, my device can only find network on LTE and 3G.
I tried this different radios too radio-hammerhead-m8974a-1.0.25.0.23.img, radio-hammerhead-m8974a-2.0.50.2.26.img, radio-hammerhead-m8974a-2.0.50.2.27.img But nothing works,
This is a hardware problem?
Anyone have idea how to fix it?
Please help!!!
Sorry for my bad English.

Yes my carrier supports 2G I live in India
Hmm, possible loose connections inside the phone?
I have the same problem, im from indonesia and im using D821, after upgrade to marshmallow, my phone only have 2g, no 3g/4g. i have solved the problem.
- first i downgrade my n5 to 4.4.4
- flash modem using recovery NEXUS5_KRT16M_RADIO.zip
- Reboot your phone
- flash again modem using recovery NEXUS5_KTU84M_RADIO.zip
- reboot your phone
- go to setting, more - mobile network - APN
- reset all APN on the list than create new apn of you mobile carrier.
- and the problem solved.
nb: bootloader must unlocked
( i dont know why should flashing the modem twice, i have try only flashed NEXUS5_KTU84M_RADIO.zip from the stock of 4.4.4 but the problem still on my phone)
sorry for my bad english.
