[Q] Force roaming on Verizon? CM7

I found several options that I thought would force roaming, but it never seemed to work.
I was at a lakehouse recently where sprint coverage was present, but weak, but my buddy's droid 1 (VZ) was solid. I thought I could force myself on Verizon, but wasn't able to.
Is this easily doable through software? Or did I just dream all this up?

I use Roam Control. Its a paid app, but it works. Its in the market.

Roam Control works for voice, but for data, it only allows 1x speeds. To get full 3g speeds while roaming, you need to flash the Verizon PRL.

im having same problem, when im on sprint signal 3g and 4g works fine, but when i roam im just getting 1x speed before i rooted my phone i had 3g speed while roaming but on the other roms i have tried only 1x,
is there a fix for this?
update: i flashed back to the original stock rom that i had backed up and im getting 3g speeds while roaming so I know it cant be a prl issue it has to be a flaw in peoples roms? can anyone confirm a actual rom that has 3g speed while roaming????

roam control no 3g

I'm using the Samsung Epic and i just bought roam control...when i press roam only it goes into roam signal but there is no 3g or 1x or any data...did i do something wrong? how do i get data to work? Thanks

go to settings from the home screen and make sure you have data roaming turned on... but if I'm not mistaken, you will only ever data roam on 1x (talking from experience, not any known document or anything)

Data roaming is on... any other possible solution?

I have used this app before without a hitch. I couldn't get data to work until I picked "roam" for the data roam guard.

You may have already done this, but ensure your data network is ACTIVATED (hold down the power button and instead of selecting power off, select data network). If it is already activated, i.e. you get a 3G signal when you get a Sprint signal, then try deactivating it and reactivating it.
Btw, you are not using a 3G toggle widget of any sort are you? The ones that actually work only work about 50% of the time (buggy), so I don't use them anymore.
If all else fails, try rebooting, wait for a Sprint 3G symbol then switch to Roam.

I thought I remember from somewhere that our roaming is onto the verizon network. And that in the sprint/ verizon agreement, that sprint customers who roam on verizon are restricted to 1x.
I think this is part of why with sprints ec05, it won't show 1x, just 3g no matter what.

How to Powersave through 3g

I was wondering how one switches from 4g to 3g(which i think people here call edge) to save battery.
I dont see it anywhere in settings so i wasnt sure what people did..
Thanks!

I think you mean 3g to 2g. This phone does not have "4g". It's just 3g with higher throughput.
I'm not sure if you can on the stock rom without a USSD code. But on custom roms it's:
Settings
Wireless and network
Mobile networks
Network mode
GSM only.
Unfortunately apps like llama/JuiceDefender can't do it automatically when you're on WiFi or not using data because Google "blocked" it. I think CM7 allows apps to control 2g/3g toggle though.

I thought if your wifi was on the 4g was turned off.
Also, on stock 2.5.- the system folder for wireless settings has a choice to only use the edge frequency. I don't know for any of the modded roms or the newer stock 2.6.- versions. Hope this helped.

T-Mobile uses 3.5g(which they call it 4g) a more advance 3g speeds so a with a 4g/3g toggle wouldn't do any good unless you wanna go to edge/2g. is not like Verizon where I think you have your Band for 2g/3g and a separate Band for 4g so what the toggle does its just turn off the 4g Band and automatically goes to 3g. but with Tmobile your have your Bands for 1g/2g and another band for 3g/3.5g(fake 4g) so using a toggle you would only be blocking 3g.

[Q] Wireless Tethering interrupted by phone calls

Sprint Gnex currently running AOKP 35 w/ Franco Milestone 3 kernel.
Whenever I am tethering via native or WiFi Tether, incoming phone calls break internet connection. I just came from HTC EVO 4g which had DDTM mode option in menu which prevented this.
I was able to access DDTM mode on Gnex by entering *#*#DATA#*#* and MSL (obtained via a script found elsewhere on this board), but whenever I try to toggle DDTM "on", it immediately reverts to "off".
I have purchased Tasker from Market and am trying to figure out a profile which auto forwards all calls to voicemail during active net connection to prevent interruption but there must be a more elegant/simpler solution.
I have already tried flashing back to stock, rooted ROM, and CM9 ROM with same results, i.e., unable to toggle DDTM on through dialer codes and MSL.

follow up
I found another option in dialer codes which allows me to set as "EVDO only". Will this accomplish uninterrupted tethering?

I know VZW can only handle voice or data at once over 3G, if you are on LTE it can do both voice and data at the same time. I am guessing it is the same for Sprint. Maybe someone else will be able to confirm this.

Um... You can't do simultaneous data and voice over EVDO (3G) on the Sprint Galaxy Nexus. It's not an SVDO device.

it is the same for sprint.
if you are on 3g, you can only do 1 or the other. limitation of EVDO.
if you're on LTE (which is not common for sprint), you can do both as the data is using LTE and not CDMA.

I realize it's a limitation of CDMA; hence reason for OP
However, previously being able to toggle into DDTM mode on my OG EVO alleviated problem while tethering on same CDMA network.
I think I have found workaround for my Gnex: *#*#data#*#<EDIT<MSL<Others/More<HDR/1X Selection<EVDO Only Mode.
Kind of a PIA, but until a more elegant solution arrives, it will work to avoid pesky breaks/interrupts in long DLs.

If you're near a wifi hotspot, wifi will continue to d/l also while talking on phone, as that's a different radio. If you're on the road, then that won't help! Unless you buy a second phone, enable that as a wifi hotspot, connect to phone 2 using phone 1 wifi....jk

I find that when I am tethering on LTE data, my data shuts off when a call comes in.
I would love to find a way to stop this. LTE and Voice should be able to be simultaneous.

[Q] FORCE 3G Roaming

is there anyway to bake this into a rom? or app?
First I'd like to say that I have seen
777kbps down or 3g speeds while connected to verizon with the sprint prl 11121.prl
unfortunately this is not sustainable
I came across this link http://mikescloset.blogspot.com/2011/10/force-roaming-on-samsung-epic-4g.html
and was able to go into QXDM and change the NV_RAM roam_pref to 0x0002
when i have the right prl installed then this will cause 3g roaming speed on verizon
the issue is that the system will change the NV_Ram setting back to either 0x00FF (anyone, but data roam 1x) or 0x0001 (sprint only).... then in order to get back to 0x0002 (Roam only 3g) you have to use qxdm... which is a pain
unfortunately you cant leave the phone on 0x0002, since it will only use roaming towers... but it would be great to have an option "roam"... which would force the roam
also Roam control does not work... or at least i cannot get it to work... it forces roam, but at the 1x speed, not the 3g speed
Thanks,
ox!
