makes calls without cellular connection - Windows Phone 7 Q&A, Help & Troubleshooting

I am going to be going to costa rica for the summer for school, and I was wondering if there was a way to make calls over wifi to the U.S that doesnt require a cellular connection because I have the arrive (no sim) and wont be able to connect to any towers over there
Also I have an epic 4G laying around somewhere so if it is possible for android then please tell me that way
also my phone is Dev unlocked also if that is required

Skype for andriod is coming soon i believe

setup a sip account, and download whichever application you prefer.

wm6 and roaming

just wrote bloody long post and pc crashed in internet cafe-
so gonna write a short one now.
i am running darkforce wm6-very stable does what i want it to do in the uk
howvever in stockholm at present and cannot browse internet or send/recieve email for what will amount to the same the problem.
the handset is obvioulsy unlocked and with t-mobile,but when abroad last year with different wm5 roms -no problems everything worked fine,have spoken to t-mobile who are about as much use as a choclate tea pot
1) when trying to connect to internet-it does nothing-if i force the connection and get it use the csd t-mobile -i get 'failed to dial' message
2) when trying to retrive pop3 email(no exchange server involved) get new message about extra charge as roaming and then it try to connect for a spilt second before displaying error syncronising
i can roam all networks pick everything up?
please help people
hello,
I've no probleme with data connection when roaming my provider is SFR (france) and roaming provider is proximus (belgium).
Have you trying with another roaming provider ?
as many as i can try telia,vodafone se ,iq etc etc
no joy-beginning toi think it is to do with t-mobile
also without stating the obvious, as and when i can find a free wifi-everything works
are you having prob only with your data connection?? back in uk (?) were you using 3g or gprs and lastly in setting/phone/ is the band set to wcdma (3g) or gprs
in uk had set data to auto all have tried every over type- but still does not explain why it worked seamless before -it either is something within the wm6 rom(i doubt) or t-mobile(proable)
but as i m traveling as soon as i get back i would like to get to the bottom of it.
It may not be your Universal - it may be your provider
Did you inform T-Mobile that you were going overseas? They need to activate international roaming on your account...
I've seen this problem before (working in a phone shop and all...), a customer from country xxxxx can't make\receive calls - because international roaming is not active on their account
Roaming worked on WM5, now not on WM6
Hi
I had similar problems. While Roaming previously (From SA (MTN), roaming in Mauritius (on Cellplus and Emtel) under WM5, I had no problems with SMS (text) or data calls.
Recently upgraded to WM6 (Laurentius' V7 VideoCall) and when landing in Mauritius last week, I could not send SMS(text) or connect data. It picked up the network. I did not test normal voice calls, since I usually dont make any while roaming. I simply used my sim card in a different handset for the week, but it was very frustrating, since Ive come to rely heavily on data access while travelling overseas (for email, skype, etc)

Could also be Radio Ver
Hi all, Could you all edit your posts and enter your Radio SStack Ver ?
And if you can remember what Ver you were on when it used to work on WM5.
As stated in the post, the 1.18 Stack had updates for roaming, I haven't had a chance to test it myself, could anyone provide feedback on roaming with 1.18.
Cheers,
Beast
dark force(excellent) and radio 1.15 will try upgrade as leave country in a few weeks
I roam between China, Hong Kong and Taiwan a lot. It appears data works better with some local service providers only. So what I do is when travelling to a new place, know which local providers data network 'roams' better with my China Mobile, by manually selecting, and trying, one by one, on the phone control panel, network selection part. Once I found one that worked, then I manually fix to that one.
Now everytime I travel to a different region, I just do, phone control panel->network->manual-> choose the known good one.
I hope this works in your situation and network providers.

Best options for international calling?

Hey guys, I'm leaving to study abroad in a few days. I'll be gone until January and I was wondering what my cheapest options are for making phone calls/sms both in my host country and home.
I currently have a myTouch 3G that I'm taking with me. I also have Skype on my laptop with unlimited calls to US/Canada. Is there any way to make skype calls using my phone?
Any other options?
Abroad, always look for a hotspot to connect to internet with your smartphone via wifi...then you can place calls with a sip provider like voipbuster, justvoip, etc. threw programs like fring or Nimbuzz.
Make sure to disable 3g, 2g, etc when abroad to avoid extra roaming kosts
Google Voice
Call t mobile and get your unlock code and get cell coverage there from a local provider. preferably pree paid so you don't go way over your budget with calling the stats.

[Q] Looking for data calling options while abroad

I'll be heading to Hungary for 3 weeks in July and will have a portable mifi (through a dutch company called DROAM) providing my internet access. I have a Sprint Evo 4G so the option of renting a sim card is out. I still want to be able to call landlines and mobile phones while I'm there.
Any options on Android that would allow me to make calls over my data connection and not rely on minutes? I'm willing ot purchase apps as necessary.
Any help is appreciated!

will an HTC 7 Pro work with Page Plus?

I am from the Android world, zero experience with WP7 and I want to buy this exact phone and possibly flash a custom ROM
and the goal is to get this to work on Page Plus (Verizon MVNO) and NOT Sprint
the phone is currently set up for C-Spire - a smaller CDMA carrier in Mississippi (formerly Cellular South)
I have access to CDMA workshop and other CDMA tools, such as qpst
I need Verizon coverage and a REAL keyboard at a cheap price ($55/month) and this looks like it could be the ticket!
I had the same question and found a post from bing searches with someone claiming to have succeeded in activating it on Page Plus. Unfortunately the person never really detailed how he did it.
I'd still like to know how it can be done.
The Arrive can be flashed to P+. I'm using one on it. You'll need the paid CDMAWS, not the hacked version.
Also, before you do this, remember that the 3G will be intermittent. The reason for this is that you cannot upload the authentication file to the phone's file system, so the phone never gets true 3G, it cycles between connecting and 1XRTT. To make this work properly, you'll need to have a ROM loaded that's a direct port from the HTC Trophy, or an Arrive ROM that has the Verizon operator package in it. I've yet to learn how to do this, but as time permits, I'll figure it out. I've got a few requests in to ansar and leadpoizon, two ROM Chefs that are heavily involved in GOLD_C (our phone's) development here.
Here's what I did:
1. Put the phone in Diag Mode, using ##MFG# on the phone dialer and connect to CDMAWS.
2. Obtain your MSL/SPC by using the HTC Method, then write it to 000000.
3. Program the phone using CDMAWS just as you would an android device; put in MIN, MDN and set your data settings to your#@vzw3g.com.
4. Load a modded PRL to put the phone on Verizon's Towers, and lose the roam triangle. (Attached)
5. Call P+ and give them the MEID of the Arrive. They'll tell you to do *22890, but do NOT do it.
6. Once they say it's active, make a test call, and enjoy your Arrive.
The steps above will give you voice calls, SMS, and spotty 3G. MMS will not work, unless you hack the registry of the phone. The phone works great with WiFi, though.
If you're brave, try forcing the phone into 1X by finding a non-EvDo PRL. You'll be showing that you're roaming, but it may yield better data results. If you do set 1X though, be sure to set MIP type (in CDMAWS) to Simple IP.
Post here w/ questions, if you have any...

[Q] Any interest in a 3rd Party GAN/UMA Service for Android?

Hello XDA-developers,
I have developed my own GAN/UMA Gateway that runs in the cloud, similar to T-Mobile's WiFi Calling and Orange's Signal Boost.
With this service you can point your GAN/UMA Client to my Gateway and I will pass the calls to and from an external SIP Provider. You no longer have to be with Orange-UK or T-Mo -US to get UMA Service!
At the moment my network is not connected to the SS7 network so unfortunately you can't just simply roam onto it. However I do have a way to register existing SIMs with my HLR. Currently this means taking the SIM out of the phone and connecting it to a PC via a SIM Card Reader. I'm very interested in talking to anyone who could make this run as an App on the phone.
Once the SIM is registered in my HLR and the UMA App is told to go to my Gateway (there's a secret menu to do this) then the phone will register and Location Update on my network.
When it is on my network, it is no longer reachable from the Operator's network, again because I can't get access to the SS7 network. I'm very very interested in talking to anyone who thinks they know how I can access SS7. I have the SS7 stack, and the skills but not the access.
Anyway for now, I can assign a UK national number to the SIM so it's reachable via the PSTN. The MSISDN number can be call-forwarded to the PSTN number (not a great solution, but OK for now).
The cost of making calls will be whatever the SIP Provider charges. (Currently I use sipgate.co.uk) I plan on just charging a low fixed monthly fee to cover the costs of providing the access.
What do you guys think? Is this something that people are interested in? I realize without a roaming service it's no better than a Skype/VoIP type service but potentially it could be a very good service if I can get the SS7 side sorted out, it's an alternative to roaming when abroad and provide better coverage at home for many people.
All comments are welcome, thanks for reading.

umm yes please!
too bad so many people passed over this thread. what if there were actually some decent data-only plans...
Would I be interested? Hell yes.
I'm currently using a Galaxy S2 on Orange with their Signal Boost app and I was crushed to hear that Orange are not offering UMA on the S3. There's no point in me having an expensive phone that I can't use at home (or most places near home). Third Party UMA would be a small miracle for me.
Interested
Hi Alan,
We are interested in talking to you about this. Can we PM?
