Has anyone tried the code *#*#4636#*#* on their Avail. Because they won't work for me.
It opens up the service center number. What are you trying to do?
Disable 3g and enable 2g or EDGE.
I know how to turn 3G off, but not switch channels. Texting and calling will still function, and possibly MMS, but no data will be used.
To disable 3G:
1. Enter settings
2. Select Wireless and Networks
3. Select Mobile Network Settings
4. uncheck the data option (can't remember the name)
is it possible to force 3g? All I ever have is Edge... a few seconds of 3g here and there... *#4636# codes either give service center or invalid mmi
It's either your baseband image (which we have none of for the Avail) or your APN settings. The APNs are free to change alot of the time.
If you have a little 3g I'd say it is your area.
I have PTel who said that I do not have t-mobile 3g coverage in my area.... I used the t-moble apn, and still didn't get 3g. T-mobile map has my area (44224) with excellent coverage.
Now from the second I turn on the 990, the E is already there... of course, when I turn on mobile netwoks, the E shrinks and has the up/down arrows.
I wonder if my short encounters with it turning to 3g was just a fluke.
try Phone Info from the Play Store. select GSM-ONLY from the drop down list under 'phone information' and it stays in 2G--extra handy for fringe 3G areas and saves a little battery. it also eliminates the random self-rebooting that some Avails/Merits have (it's something wrong with the 3G/PRL update--it causes a Kernel Panic)
the default is GSM (Auto PRL) which keeps it in 3G and falls back to EDGE if low signal or lack of 3G coverage. i have not yet played with the other settings.
NEVER hit 'radio off' it forces the phone into Airplane Mode and it will not go back off even if you turn Airplane Mode off, it stays stuck in that mode until you reboot it
Alrighty... I just found out that t-mobile is "farming" their 1900. Looks like I will only get 3g in areas that are farmed. Avail needs AWS 1700&2100 for true 3g from my provider. Oh well, still a nice phone to have!
I just got a blackberry 9300 and I can switch between 2g and 3g. my friends GS3 can also fall back to 2g/3g.
I know this is late but try this code *983*3640# it brings the screen which preferred net work type you want as default.
good call! worked. but I didn't change any settings since I am not sure what each does. maybe in time.
No Problem glad to help , should you have any other question am here
Thank you for the tip micallan_17!
Just here helping
I cannot change preferred network type with *#*#4636#*#* and the radio is also off and won't change.. The phone has gone to airplane mode because of it. Please suggest.
