So I followed all the directions on making my tab a phone, seemed to work well. I unlocked it, backed it up first, etc.
It all seemed to work well, with some minor exceptions.
1. I can make phone calls... sometimes. Sometimes I can call and it works great, other times it says it is dialing but there is no dial sound and it never connects.
2. I can send SMS... sometimes. Sometimes it just sends and recieves, other times it times out.
3. My icon for data connectivity says it is Edge and never shows 3g.
When I pull down the status bar it says AT&T, this was a T-Mo Tab that I unlocked and am using my AT&T SIM from my iphone.
Do I need to re-flash the modem? or did I mess some other step?
Thats all ur going to get. You can use rotohammers switcher app in the dev section. It gives u 3G or 2G+voice.

I would be ok with 2G+Voice actually... If I am doing much data I am usually on wifi anyways so 2g would be just to get email notifications.
My question is can I get the voice and sms (data) to be reliable? I would like to make a call each time I want to make a call.
I will try the switcher and see if setting it manually to 2g and Voice will make it more reliable.
The switcher also flashes a more reliable 2g modem, I used it for a while, still do when I need to. Rotohammer rules.

I am having a very strange issue:
Whenever I am at home, and my G1 is connected via 3G, I cannot use data or make/recieve calls. If I enable the "Use only 2g networks" checkbox, it reconnects via EDGE and works perfectly. I currently have a service request out with TMO which should resolve in the next 24-48 hours, but I was wondering if anyone had heard of this issue.
TMo has no idea why I'm not getting signal, the problem continued even when I reverted to stock "Cupcake".
Things I've tried:
Reverted to stock firmware and unrooted phone (Didn't work; same symptoms)
Call T-Mobile, they removed and re-added me to network. (Didn't work; same symptoms)
Swapped SIM card at T-Mobile store (Didn't work; same symptoms)
T-Mobile service request in my area (Results pending)
Things I am going to try, but haven't yet:
- Return to stock firmware, reinstall CM 4.2.7.1
- Try an older CM like 4.2.4 or 4.2.5
- Connect to WiFi for data connection, see if this replicates the problem as with 3G
- Enable data roaming.
The fact that it only happens at home leads me to believe it's not a problem with the phone, however I'm more than willing to do more to rule it out.
Phone Specs
T-Mobile G1

Baseband Version 62.50S.20.17H_2.22.19.26I

Mod Version CyanogenMod 4.2.7.1
Build Number DRC83
Dont tell T-Mo that your rooted thats a big mistake right there, that can be used against you if you ever have to get the phone replaced.Play around with the apn settings and make sure "always on 2G" isnt checked in settings. Maybe your house isnt in the small 3G coverage area, or your phone cant connect to it. Why would you think data and talking at the same time would be possible? Its either you answer or you stop browsing the web.

Yes, thank you, I know not to tell them that, they have zero idea. I also forgot to mention they did swap out my SIM card at the store.
Read what I posted. Turning on "Always On 2G" is the ONLY WAY I can make calls and use data at home. When that isn't on, the phone says it has a 3g connection with four bars, but will not dial out, take calls, or connect to web pages. I've also verified my APN as epc.tmobile.com which is correct, and this affects my voice and data communications.

Try another rom to confirm you cant get 3G, it could also be HW failure.But just try a older cyanogen or something else.Ive cant get a 3G signal with cyanogen roms for long but with a hero rom i seem to get 3G(maybe its my imagination)

It fails on both stock (untouched, unrooted), and CM. I'll try an older CM just in case though.

Rebooted phone between each of these tests:
3G With WiFi enabled: Same result, can't dial out.
Data roaming enabled, Wifi Disabled: No signal at all, 0 bars with "X" symbol.
Stock firmware: 3G won't dial out, forcing 2G works.
Downgraded to CM 4.2.4: Same symptoms.

What ! if you have 3G coverage you can talk and access data at the same time.
That is what 3G provides.

That's not what I'm trying to do! When I am at home, on a 3G connection, I cannot do ANYTHING. That includes text, voice, data, web, ANYTHING. If i force it to use Edge, all services work properly. This is not acceptable. T-Mobile's coverage map lists me as in a strong 3G area. It SHOULD work.
I dont know what to say, except stay on edge, you alreadt sent a req to tmo.
I am having the exact same problem. Would love to learn what you found out.
I have unlocked my G1 to use with my AT&T SIM card, and sometimes, my friends text me saying that they called me a few times and I didn't answer, but my phone has not rung at all. So I was curious and called my phone with a few of my friends' phones, and it does not ring sometimes. Out of 13 different calls, only 3 of them rang on my phone. I think texting works perfectly fine though. Can someone please help? Thank you!
I can't help you right away but I can guide you to a thread where people are discussing similar problem and trying to find an answer.

if you are using a Tmo G1 on the ATT network, then I believe it will be EDGE only. I could be wrong, but I thought that EDGE didn't allow simultaneous voice and data. Maybe you've got something running in the background and it's blocking the voice calls. Try turning data off, just phone only and see if it works.

I don't think that it works like that. Voice calls should still come through, but data will be blocked when it does. This is because the network doesn't provide enough bandwidth to support both at the same time.
I have done some searching around on the internet trying to find a way to set my captivate to use edge/2g network only and I have not yet been successful. I have tried using anycut, and a method that uses a special menu by dialing *#*# a number and #*#* and no luck. Are there any sure fire methods for doing this?
I just used the method of punching in *#*#197328640#*#* Clicked Debug Screen then Phone Control then UE State Control and chose Change RAT to GSM.... after that wait a few seconds and your 3G icon should change to E. I just tried this method a few minutes ago with success
Awesome just what i needed. I tried a similar shortcut dialer but had no luck. Now if only there were a way to create a one or two click shortcut for this

I got the same problem i unlocked my Captivate im on 3g speeds but the icon stills shows Edge
Hi, THANKS FOR THE TIP!!! Sometimes my Captivate runs out of signal.. GSM now is on 850..
I was wondering about this:
-Debug Screen > Phone Control > Network Control > ""Adquisition Order""
What this stands for?
Thanks..
Cant answer the last question but something I found incredibly useful was to download SamServMode from the market. It takes you straight into the service menus without dialing that string.

Thanks! You know, my Captivate doesn't seem to be very smart.. When it was on 3G (RAT to WCDMA) in a dead zone, it lost all its signal, and i couldn't send any SMS or call (While my iPhone 3G still had signal and funcionality) .. And now, on GSM (EDGE), my Captivate has 3 or more Signal bars than before...
BTW, #*0011* is the same menu!
I wish there was a quick toggle for this like there was using SBSettings on my 3gs :-/
I have NO 3G available at all in my area, but when I drive 1hr 15 mins to school, there's some 3G there. Would be nice to be able to toggle this without all the input you seem to have to do, as I feel I'm wasting battery with 3g turned on all the time and it not available
Samservmode works, and its better than remimbering that number every time. Even though you still have to navigate through the menus

Don't know if anyone else has had this issue in this forum, but I have found several others with same issue in other locations. No one has come up with answer and HTC has been no help.
If I lose my signal, due to location or if I drop off of wi/fi and go to cellular data, it seems that the phone loses the ability to make or receive calls or texts. For example, if I leave a strong signal area and drop to edge service or none, and then return to a good signal location, the phone shows full bars and 4G but if you try to make a call it will not connect or if someone calls in they just go to voice mail. I have to reboot the phone and all is good. This seems to happen several times a day, never any issues with iphone 4s or Galaxy S3.
Here is what I have done and then after the fact HTC sent me an email telling me to do same thing.
1. Got new sim card.....HTC is convinced that the sim from my iphone was not good.
2. Exchanged for new phone.
3. Ran phone without syncing to my google account or any downloads.
Still same issue with losing connection. Most of the time I don't realize it until someone says, hey I have been trying to call you. I reboot phone and, wow, several missed calls and bunches of texts.
Let's see what they have to offer after the complaint.
Thanks

Hey, similar problem here
The difference is that I only loose mobile internet when disconnecting from wifi in AOSP roms (and GE), on sense roms it seems fine.
I have however noticed a pattern, it might help some one figure it out, but it might help you too.
I only lose Internet when disconnecting from wifi If 4G Is on, if I force my phone to not use 4G, then I don't loose network.
Also, if I do loose network, a reboot isn't required, you can simply Turn airplane mode on and off, that has always worked for me.
Ps: to force the phone off 4G I do the following :
1: open dialer
2: type : *#*#4636#*#*
3: go in "phone information"
4: under "Set preferred network type" set it to "wcdma preferred"
The reason I prefer this method is that it's always the same no matter the rom.
Pps: my baseband is 4A.17.3250.17, if that matters for any reason.

Not solved...try everything...but no luck....
I get it too seems like the phones radio doesn't switch frequencies as smooth as other phones.
I downloaded this app to use because I wanted to turn off LTE at work. On 4g, I can't send out texts b/c the reception sucks, but I have full bars of 3g. Sooo, I tried to do CDMA only using this 4g LTE switcher app and now I cannot connect to any cell tower at all?!???! Help???

Relax... and reboot your phone. That app looks like nothing more than a way to access the phone's hidden Phone Info menu that on some phones you access by dialing *#*#4636#*#* or with an activity shortcut. What you're seeing is part of the phone, not the app. Anyway usually changes in that menu don't survive a reboot. and even if something did survive a reboot, just retrace your steps and set anything you touched back. like "LTE/CDMA auto (PRL)"

Thanks for the reply. Unfortunately, I have tried all of the above, including a full factory reset. I did change everything back to default in that app, rebooted several times, etc. Dialing *#*#4636#*#* doesn't do anything for me. Also, it's very strange. This morning I woke up and checked it again and it seems like only the 4g lte radios are working. I can get 4g signal, but no 3g or edge. I can't make any phone calls or access my voice mail, but I still can receive sms/mms and send/receive data. I'm pretty much at a loss...Any other suggestions???

There is no edge on Verizon, it's LTE, evdo and 1x. You could try doing a PRL update. It's right under system update I think.

You could try reflashing your current android version with RSDlite. I don't know how different it is than doing a factory reset, but try it nonetheless.
