[Q] error code 67 and carrier tower

hey, my evo is rooted and am running sense 3.5. this is the new rom i got because i thought it might help the problem. however, it didnt work. i am trying to use 3g but a message saying error code 67 keeps popping up. how do i get my 3g to work? i thought i had to update my profile, bu the rom doesnt have that so i installed a new rom, which didnt make a difference. great rom thought!
also, i dont like sprints service, which i why i want to use verizons network. i can roam manually, but i want to make sure i am using verizon and not another carrier. how do i check which tower or carrier i am using.

You need a sense 1.0 rom or a stock rooted rom to update prl and profile, you have to change your prl manually to force vzw 3g use it too much and sprint WILL boot you if you force roam normally you will only get 1x on whoever has the stronger signal in your area could be vzw could be usacellular could be metropcs could be any of sprints subsidiaries like virgin or boost manually changing your prl to a vzw one will guarantee vzw coverage BUT use too much data and get the boot use too many voice minutes get the boot and while using vzw they will use your anytime minutes no free mobile to mobile or nights and weekends so be prepared
We are legion, for we are many

prl
so how can i change my prl so it only roams on verizon?
if it is always roaming on verizon, will there be an additional charge for the 1x signal i will be getting?
i dont use that much 3g nor do i talk a lot. however, i text a lot! will that affect any additional charges?
i want to use vzw without any additional charges or having to get into any problems with sprint nor verizon with our contract.

If you continue to roam on Verizon you will receive a letter from Sprint telling you you need to cancel your service.

Unlocked Incredible 2 but data plan and 3g not working

Hi All ,
I had Vz droid Incredible locked. Last week i moved to att and so unlocked the incredible 2 with some unlock code . It started working on att network i'm able to make call and receive calls. But the data plan (mobile internet )and 3G is not working. Please do you have any suggestion on how to get this working.
Vivow HBOOT - 0.98 and android : 2.3.4
thanks
kevin.

You will never get data because the radio in the dinc2 can't pick up the frequencies of at&T's data network.

I thought you could get 2g speeds on ATT and Tmo.
Check in your settings to make sure you have all network settings set appropriately.

OP, are you running VZ's factory (HTC) ROM or custom ROM (Sense or ??) and was your DI2 unlocked by code via eBay or by VZW Global Support while you're on CDMA with Big Red?
Can you switch to GMS/UMTS setting - and check to see whether it's picking up AT&T and/or T-Mobile - and you are in the US, correct? Are you on prepaid or postpaid with AT&T and is data enabled on your account?
Mine was rooted & unlocked via VZW, and GSM voice/SMS worked fine - running SkyRaider, CS's lates CM7.2 & NJ's Sense2.1/3.0 stock roms - (E)dge or 2.5/2G data works on my AT&T Gophone SIM with data but won't work on T-Mo unless I subscribe/add the data option. For overseas travel, my China Mobile HK prepaid Sim worked great for voice, SMS & broadband on PAYG basis here in the US too - roaming on its partners, either AT&T or T-Mobile (it's on Edge/GPRS only, I think - as I don't need to run up pricey charges for broadband access, use WiFi when I'm on this CMHK account) - when we're in Bermuda last month, same Sim roamed on DigiCel and it showed 3G connection.
Most likely, you will need to clear cache & reset your DI2's browser settings, and maybe modify the APN to get broadband/MMS to work properly, assuming that you are provisioned properly ...

Thanks for your replies.
yes i did some APN settings and mobile internet worked. But working for only Edge data connection not for 3G. This phone is still having VZW ROM (android build), But if i root it and change the android to ICS, do you people think it will work on 3G.
I need to have 3G running on my phone because of att poor service, I'm using the micro-cell to get the att service at my home (micro-cell works with 3g phones). Any suggestion please.
thanks

How do you set 3G data only, dont want to use LTE to safe battery life.

In mobile networks switch network mode to wcdma only.
Edit: could be hspa only, depends on your model.

4g is not lte by the way. If youre on lte it says lte not 4g
Sent from my LT28at using xda premium

lte is 4g on most roms that I have seen. Although I never used the lt28at just the lt28i and lt28h where hsdpa+ is called h+ and lte is called 4g.
There should be a toggle that you can download that will be able to click 2g 3g or 4g. I know on miui there is a toggle for that.

If you're using a Lt28at like me, you can't toggle anything but LTE. SInce the boot loader is locked it will give you the option to pick a different frequency, but will automatically revert back to LTE. Sucks.

The version i have only give me LTE data, or no data at all.
It is locked to rogers.
Can it be changed so i can use 3G only?

No. Your boot loader is most likely locked also. You can only choose LTE. The only other option is to find the APN setting for 3G and enter it in your mobile networks and choose it. It will only use 3G but your phone will always search for LTE by default. You will save some battery by going that route. I don't know what the 3G apn for Rogers would be, however or if there is one. AT&T has a separate apn for LTE and 3G. Maybe someone else here knows more...

Yea, i just found out this can not be unlock... thinking android can be unlock easily since my last 2 phones can do it.
I will find the 3g apn.
Hopefully someone can find a way to unlock it and use other rom..

Still having bad connection with new modem

How do I check if my T-Mobile phone is roaming correctly on AT&Ts voice network? I can find the data roaming option under settings but since I have updated to 4.3 ROMs and above the voice roaming setting disappeared.
I have T-Mobile postpaid non-contract so I should be able to voice roam on AT&T for free. I am having spotty coverage issues after updating to 4.3 ROM and I have verified that I am on new MK2 modem that I successfully loaded through ODIN. The last time I had this spotty issue it was caused by a ROM that turned off my voice roaming. Does anyone know easy way to check whether voice roaming is enabled? There is a big difference between T-Mobile's prepaid and postpaid networks in Southern California.
I am running Infamous 9 with ktoon kernel.

[Q] Samsung Galaxy S3 I747M not registered on network at low signal

I have a SGS3 I747M from Canada Fido and now using in Pakistan after network unlock. It does not register on GSM 2G/3G network whenever the 2G signal strength drops approximately below -70 dbm. It can neither make nor receive a 2G call
Things tried so far
tried all available modem drivers from XDA Forums
tried on stock Jelly Bean 4.3
tried on stock KitKat 4.4.2 (currently on it)
tried changing to airplane mode and back
tried change network mode to 'GSM Only'
tried signal boosters from android market
But nothing works.Only where signal is strong around -50 to -60 dbm it is able to connect to the network.
have tried it on two different operators Mobilik and Warid but result is same.
What can be done to fix it??

I'm not so sure about this but perhaps the device doesn't have the right frequencies (being a Canadian variant).
That being said, You could try different baseband and modem. I'm not sure if will work but worth a shot.

I747m does support gsm 900/1800 which are supported in my region.
I have already tried all I747m modems available on xda forums but i guess these are all for canadian networks.
Can you suggest if i can use a modem for another s3 variant released for pakistan.
Would any custom rom/modem be able to fix this?
Problem is only when it detects weaker signal. Though other handsets connect comfortably in the same spot. If i move around a bit where signals improve, it connects and works fine
could there be a low signal threshold programmed in this device for power saving or something

Only flash things that are for your device model. Flashing s different devices modem is a great way to hard brick.
Sorry im not sure about a solution. Just wanted to at least warn you against flashing a different modem.
Have you contacted your carrier to see if they might have any useful info for you?
