I was thinking of posting this in the general section but posting it here seemed more appropriate as I think the issue at hand is of a more technical nature. If this is not the case I apologize in advance.
I recently purchased a Black HTC Magic (Rogers branding) for use on the AT&T network here in the states. Since then I have had a very difficult time initiating calls while connected via 3G (UMTS/HSDPA). Even in high or low signal situations.
Unfortunately there doesn't seem to be any consistency to my ability to make a call while on 3G. At times 5/5 calls would be successful and other times 1/5 calls are successful (the latter being true more often than not).
Suspecting there was some issue with my device being on 3G I forced my device to use 2G (EDGE) connections only. At which point my reliability issues go away completely (from what I can tell).
I don't experience any strange issues with using my data connection while on 3G/2G so it seems to be specific to voice.
Another interesting thing to note is while trying to initiate a call with the Google Voice application on 3G, I experience the same call initiation issues as mentioned above. Google Voice works as expected while on 2G.
I experience these issues on the original shipping Roger's ROM, as well as all the other 3rd party ROMS (HoFo, Cyanogen, etc...)
Here is information about my device from fastboot...

Is it possible that my SIM card may be causing issues?
Anyone else with a North American Magic experiencing issues on AT&T? I appreciate any help you guys could provide.
your phone is ok
perhaps you might have heard... iphone great phone...AT&T absolute **** network
with dropped calls, and constant diverts to voice mail. dont sweat it. its AT&T not
your mobile.
I would have to agree that it's probably the network, although I might be wrong. I also have a Rogers Magic running on AT&T in Arizona, and I have this issue as well, but not nearly as frequently as you do. This same problem used to happen from time to time with my HTC Fuze and my BlackBerry Curve.
I've had a variety of different devices on the AT&T network (Northeast/Washington, D.C) and although yes I have experienced AT&T's wonderful network. What I'm experiencing just doesn't seem right. Makes me wonder if it's my SIM or particular build....

Moved into general discussion forum as not related to android development
if you are not using a newer sim card i would start by changing that. i was using an older 3g sim which i have used with many phones and i found that by changing to a brand new sim the few connectivity issues i had have gone away
which ROM?
Just a question, but which ROM is everyone here using? I, too, experience the random inability to make phone calls over HSDPA. I was told by an at&t rep in-store today that the Rogers Magic does not 'show up' in their system as 3g capable. Pure bs is what I think, but lets rule out software, yes?
If it is not your sim card then it is most likely your network.
Calls over 3G/HSDPA is fine on my Magic and was also fine on my Nokia N79 using the same Cingular SIM card that I have. However, making outgoing Google Voice calls over 3G/HSDPA is a no go.
Yeah...making calls was fine on my Unlocked Touch Diamond, too...but it's NOT on the Magic (32a).
SO...I'd just have to guess that it's *probably* not the SIM card.
I was told (via an exceptionally helpful phone rep) that the "voice 3g" in my area is not very good, but that the "data 3g" is much better. Which (she says) is why I have trouble making phone calls, but that data works fine.
I don't think so...but without *that* answer, I'm left with the AT&T stock "well, we don't support *unlocked* phones, sir, we can't guarantee that they'll work with our network".
ARRRRRGH! REALLY?! SO, phones with the same chipset, using the same technology won't have the same results?
PLEASE, FCC, INVESTIGATE THIS B.S!
Hey radikaled, I have some new developments with GV and outgoing calls. If I set the GV call options to "ask for each call" the issue of calling over 3G appears to be alleviated somewhat. Basically, when initiating a call, you will be prompted on whether you'd like to make the call via GV or not. At this point, wait a few seconds at this prompt and then choose GV. So far the call has successfully connected 100% of the time.
It appears that the data connection is too slow to establish fully over 3G, therefore, the call fails if you don't wait the few seconds before choosing to call via GV.
Let me know if this works for you.
I too had issues with my ROgers Magic unlocked on ATT. When I first got it I used the original ROM and then the HoFo ROM. Both had similar issues with dropping calls when switching from EDGE to 3G and back. I also dropped more calls than normal.
I recently switched to Cyanogens ROM and new radio. I have not had any issues since and then. Calls and switching is very stable. Also the clarity and volume is also much better. Just my experience. Very pleased with this phone on ATT now.

Thanks for sharing your experience. May give CM ROM a shot.
Good read.
Nice post. Interesting topic.
I tried to send several other users your way...I'm sure they eventually checked this out. I've come across this issue with some other folks recently too.
Best of luck though.
Me TOO!
I also have a similar problem. When connected with HSDPA, about one third of the calls I make fail immediately, even with full signal strength. I then wait a few seconds and dial again, and it works. I actually am using the sim card from a previous nokia POS phone I had from two years ago; the ATT people just took it out of the previous crap phone and put it into my poor fuze. How much does a new SIM card cost? Can I get a new SIM card without att bothering me about not having the stock rom? I'm using Da_G's clean fuze 23008 winmo 6.5 with the 1.12.25.19 radio. I live in the Youngstown, Ohio area (between cleveland and pittsburgh), so cell reception on any network is pretty bad, but it seems the ATT/cingular network around here is particularily bad. Any ideas?
Let me note: I am not a dev nor programmer.
With the similiarities of the P6800 and the Verizon 7.7, I threw together a rom w/ stock SCH-I815 samsung/verizon kernel using the P6800 frameworks and apps into the Verizon 7.7 and removed most bloat. The LTE/Verizon antennas aren't recognized by the device at all but everything else was working.
Now, you can't swap the phone.apk's around without the framework's else you'll experience FCs. So obviously I'll need to use the base stock apps and frameworks and go through the 2 framework files hunting about.
Has anyone else with the Verizon 7.7 taken a look into this?
I'm curious if you've made any progress on this?
Not yet, probably be a week before I even look through the files again. But I believe it's fully possible to get phone use

i think you will need to find samsung modem for verzon networks, does verizon have a galaxy note or sgs2?
although your modem firmware probably has voice disabled, may have to find modem manufacturer and try to flash custom firmware.
good luck, wish you the best.
I'm happy enough using GrooveIP for google voice calling. What I'd really like is if we could activate the phone profile in bluetooth (or will that just come with enabling the proper phone part in the 7.7?).
As of now i can use GrooveIP and bluetooth to listen and speak, but it won't let the bluetooth device answer/hang up/transfer address book/show caller ID (on the Verizon LTE 7.7)
Doesn't verizon require some sort of signed telephony to work properly on their network

I got no idea but with the other packs it didn't detect the radio at all. This is keeping the vzw radio partition stock. I like the ideas and really wish the note was verizon as that'd help figure things out.

It does for LTE but cdma service doesn't use sim

Seeing as your data account won't have any provisioning for voice usage, even if you DID get a working modem and a modified framework to allow for phone functionality on the device, I doubt that you'd actually be able to made or receive a phone call due to Verizon's limitations at the account and provisioning level anyway.
Point is, it's a CDMA device, and thus your service is attached to the device itself, not the SIM card (except for LTE data). Basically, you can't just provision service to the SIM card alone, and then simply swap it into a different device. So if you got the modem and the framework working, and you called in to Verizon customer service and asked to provision your line for voice, they'll just be like "Umm, no... We never INTENDED for you to use that device as a phone, so no... You want a phone? Buy a phone. You want a tablet? Buy a tablet. You want to do both in one device? We won't allow that because that loses us money that we would be getting by having you either subscribe to two lines, or charge you extra to tether..."
There is a much simpler solution however.
Ditch ANY CDMA carrier in favour of a GSM carrier instead, preferably one that uses the same compatible frequencies adopted by the rest of the world, like AT&T (and MVNO's based off of AT&T's network), and buy the P6800.
The moral of this story is this: if you want the latest devices, with the best features, you're NOT going to find them in the north American market, EVER, at all, period; you're just going to find watered-down, gimped, bloated, and locked-down versions of the international models. You HAVE to import. If you're going to import, you HAVE to use a GSM service provider... That's just the way it is. It sucks, I know, but it is what it is.
I would have to agree, the GSM version would be best. It would be near impossible to make this happen. Of course if I was stick with one, I would try everything I could as well. I'd probably fail miserably and go for something like GrooveIP.

I move my SIM between devices all the time and have never needed to call VZ to provision the new device. Voice and data just work.

I can CONFIRM the following:
I have a VZ tab 7.7 with 5GB data plan and I have a VZ Razr with voice/unlimited data plan.
Both are LTE devices and hence use (micro) SIM cards. In "My Verizon" even the tab has a phone number assigned to it's "line". A call to that number just rings but obviously nothing on the tab.
BUT...
Put the tab sim in the phone and YES it will ring if you call that number! Even TXT in/out works! I assume they will just charge me per txt and per min phone use BUT IT WORKS in a PHONE.
And the kicker is, the unlimited PHONE SIM also works in the TAB! I immediately get LTE data and can surf with the tab. Of course at that point calls and texts to that phone number are "ignored" by the tab's neutered modem.
Lesson learned:
IF there was a way to flash a modem, say for example from the Samsung Galaxy Nexus to the VZ 7.7 TAB, we would have a full supersized phone in our hand. Only downside, no earpiece. So only speakerphone or BT calls I guess.
Anyway, after a little more research I also found this very interesting article:
http://www.phonenews.com/verizon-affirms-unlimited-smartphone-sim-card-usage-in-hotspots-tablets-lte-ipad-20053/
Hope this helps bring a little light into the messy CDMA/LTE darkness
I have swapped my Galaxy Nexus SIM in my VZW LTE 7.7 numerous times. It works. I'd love to have voice on the VZW LTE 7.7, then I could possibly do it all on my tab. I'm no developer tho ;p
I have read a bunch of threads all over and done some searches but cannot seem to find any clear definitive answers on a few things. I am looking at grabbing the Samsung unlocked S8 and want to know for sure if anyone can confirm what does and does not work on VZ with that model? I am pretty sure of the following, but anyone who has one on VZ and can help me out would be greatly appreciated.
- WiFi Calling does NOT work on VZ with the unlocked version. I am pretty sure based on what I read on this.
- VoLTE and HD calling DO work on VZ. Again, pretty sure from what I read but it is hard to find definitive answers anywhere.
- Any app based WiFi calling would still work (so using stuff like Signal or any app that uses data to make calls could make WiFi calls even if the VZ network WiFi calling does not work?)
- Video calling DOES/DOES not work? Cannot find any answer to this.
- Voicemail still gives you notifications/works like normal? I think I read someone say that Visual Voicemail does not work, so the app that lets you just tap and see and instantly listen to VM would not work and you would have to dial *86? Not sure here and clarification is appreciated.
- Any other significant issues or things that don't work or are affected that I have missed?
I think it is pretty bad that phones can evolve with tech and you can get a phone several years and models newer than an older phone, but because one is carrier locked version, it has a ton of features that the newer phone can do, but won't because of carrier BS. Again, all help is appreciated. Thanks!
Visual voicemail does not work. HD calling works. I dont do wifi calling. I dont do video calling. I have unlimited data and mobile hotspot works flawless.

Did you decide to purchase the unlocked S8 for use on Verizon? Has it been a good experience? I'm thinking of buying one since I have the grandfathered unlimited data plan and I'd like to be able to use the mobile hotspot without having to root. Although I don't travel too much, having the option to use my phone in another country by popping in a local SIM is definitely an attractive feature. Thanks in advance!
I'm making a broad post as a last resort on this, the only two thread on it I found were dead ends.
I've exhaustively searched and trialed different roms/firmware/CSC to get my already activated verizon sim working on my SM-G955FD.
I already know Exynos has no CDMA, neither did the HTC U11 that I had for a short while, and that didn't cause me any issues with outgoing calls. the VOLTE seems to be doing a fine job.
I PM'd two people on xda who said they were using it stock with no problem, but haven't gotten any replies on what steps they took. I can't even get data working regardless of APN or CSC. It simply refuses to connect to the network. I also hate what verizon did to the settings menu on this phone. If I didn't have the GFUDP, I would have moved on a while ago, but I use too much data.
Of course I know I can get the verizon snapdragon model, but I need root. I simply cannot function without titanium and the fact that android, to this day, has no official perfect backup really grinds my gears.
If anyone else has had success with this, please point me in the right direction. tia
Phone: Galaxy S8 / SM-G950W
Network: Telus
Problem: This is the strangest thing I've ever seen! My phone is showing incoming calls from my wife's number and another relative as "Private Number". All other calls are identified correctly. Their network is 7-Eleven Speakout.
The strangest thing is, if i take my SIM and use it on a different phone, their numbers show up just fine. Also, if i put another SIM from a different provider in my S8, it also works fine. I even changed the SIM from Telus and got a new one but it didn't help. I've reset the network settings on the phone, reset the data on the phone app, nothing worked.
It seems that the problem only happens when I use my Telus SIM on that specific S8 phone!
Unfortunately, wiping the phone is the least favorable solution as it's not rooted and I have tons of apps that it'll take considerable effort to re-configure them. I don't backup to samsung or google for privacy reasons. Used to use TitaniumBackup, but since no root exists for this phone yet i cannot use TB in this case.
My question is: Does anyone knows the process of call identification on android phones and may have a good guess why such a behavior may happen? I have a bit of a technical background so i may be able to understand any technical explanation...
I need help on this, as now i have to answer any private number that calls me when i'm away as it could be a family emergency, unfortunately telemarketers and spammers are not making my life any easier and i would love to be able to block all unknown calls again like i used to...
Thank you all for your help in advance, this is one of the strangest issues i've seen and i only ask for help here after i depleted all other ways...
Cheers!

A friend is having the same problem, albeit worse - it's all incoming calls show as unknown.
Swapped my SIM in and it's fine. Swap back and it's stuffed again. The suspect SIM works fine in my phone tho.
Even got a new SIM and ported the number to it, but same problem.
Out of ideas to try.
Looks like it's time to replace the phone
