I don't know whether I should ask it here or shouldn't.....i was very happy doing VOIP on my Vibrant.....now suddenly my company has blocked VOIP also none of the messenger's are getting log in...
Only my phone's Gtalk is working...but no VOIp. is there a VOIP application which can bypass this blocking. I tried several application from Market...but none seems working.
My sip provider is NYMGO (www.nymgo.com)
Please if any one can help??
Bump.....85 views no reply...come on guys....help me out...
I don't understand the problem.
Are you saying T-Mobile is blocking VoIP over data?
Are you saying your employer is blocking VoIP on their WiFi network?
My employer is blocking VoIP on their WiFi network.
Make friends with one of the network admins and ask them to unblock the ports NYMGO uses. Seriously, they obviously don't want you using unauthorized apps or services on their network. Many companies, including mine, have strict policies in that lead to disciplinary action, up to and including termination for any unauthorized use of the company's network or the circumvention of any security policies in place.
First step would be to talk to the network admin and find out what changed on the network and if they could re-open those ports used by your voip. If they tell you they can't, you're SOL. It's the company's network, not yours, they pay for it and therefore they decide how it's used, not you. If you had to manage a large corporate network you would understand.

I have a Siemens SX56 using AT&T Wireless as a carrier.
The phone is running the following:
ROM Verison: 3.14.03 ENG
ROM Date: 09/27/02
Radio Version: 6.12
Protocol Version: 324e4
My question is:
I would like to connect to a traditional ISP. I have talked to AT&T and they said when I go to the internet, I have to connect using their GPRS network. They said that if I used another ISP I would not have to pay them to use the internet. DUH! this is what I want to do. Any advice would be appreciated...
Thanks!!!

You can connect to the Internet using GPRS. This, in essence, would make AT&T your Internet Provider. You can choose to get your mail at your existing provider (but you must use AT&T's server for outbound mail). Other than that, your 'normal' ISP has nothing to do with you once you connect through AT&T using GPRS.
You could, theoretically, also connect using the GSM as an ordinary modem, by dialing your old ISP, making what's called a 'GSM data call'. This would however limit throughput to roughly 9600 bps, and it would not have the nice 'always on' property of GPRS. It would be cheaper per bit (in most cases) for large downloads though. Go figure.
i want to make a gsm data call
I do want to make a GSM data call. at&t charges an arm and a leg for data access, that usimg my regular ISP even at 9600 baud would be great.
when I try to set up anything other than GPRS, it says "there is no answer". I called siemens and the said at&t disabled anything other than GPRS.
what I want to know is can I enable that ability which I know the phone can do?
Thanks
Bob
GSM data calls can be made from most phones, but AT&T may have disabled this call type for anyone but those paying for a 'data subscription'. With most providers a data subscription just means you get a seperate phone number in order to be able to receive incoming calls from analogue modems.
GSM providers are weird. For instance O2 in The Netherlands blocks fax calls for some unknown reason, but passes GSM data calls.
I must not be clear...
OK... I must not be clear, so I will try to be more clear in my question.
First a little background:
I have AT&T wireless with a data subscription. My current subscription is for 8 Megabytes per month. I would like to use the web, but with only an 8 Megabyte limit (which is AT&T's highest data level subscription that you can buy) I can not do much on the Internet.
I know that a GSM data call is slower. I know that it is not always on like GPRS. Because of the data limit of my current AT&T data subscription I want to make a data call from my phone to my ISP.
I have setup a ISP connection profile in the connections area on the phone. When I dial the ISP the phone responds with a message that says "the number you dialed is not answering" this is a text based message, not a voice message. I know the phone is answering because I can call it from my home pc or just dial it from the cell phone and it answers. I was told by siemens that AT&T turned the GSM Data portion of the phone off. I am hoping they turned it off with software and its a setting or something I can change in the registry to enable it again.
So in summary:
I do pay for a GPRS data subscription ($25.00 for 8 Megabytes / month)
I would really like to also use GSM data as an option for getting to the Internet when I do not want to use up my 8 Megabyte limit on GPRS.
I really have appreciated your comments and your help. I hope I am being more clear in my question now.
Thanks,
Bob
I'll try to be more clear as well then...
Try calling your provider and see whether they support GSM data calls from 'normal' subscriptions. And with normal subscription, I'm not talking about whether or not the subscription has GPRS, but I mean any subscription that doesn't get you a special phone number for incoming data calls.
There's plenty of providers that do not provide normal data calls, even to subscribers that pay extra to get GPRS. Most of this practice did end when WAP was believed to become big, but some may have limited data calls to their own WAP access numbers.
Should your provider still offer separate numbers for analogue and ISDN, try calling both types to see what happens, and do play around with both call types (analogue & ISDN) from your XDA. (Under 'Settings' / 'Connections' / 'CSD Line Type' in modern ROMs)
Good Luck...
Similar issues
I am trying to do the same thing with my 02 XDA, and i get the same message saying it is not answering. However, i can dial my ISP using a GSM connection, as i have done this using my nokia 7650 connected via IRDA to my PC, and useing it as a modem. However i cannot get the same connection to work using my XDA. Very strange, so if anyone can help.
Unlike users of networks such as Three/Telstra, who sometimes roam while this is undetected by their Android phone - my situation (and those of many other users) is similar, though not so easily solved by tweaking APN's.
In this particular case, Android detects the network of the own provider as roaming, resulting in a phone that prevents synchroisation with Exchange irrespective of settings that force data connections to be established during roaming.
I have called my provider, HTC and even an independent third party for a solution. Initially, they were all blaming other parties but themselves, but it seems that the real problem is not with the provider or HTC, but it is with Android; when my SIM card was inserted in a Nokia or WM smartphone, it worked normally, but it did not in every other Android based phone.
So, the question that remains is obviously: can this problem be solved - either by tweaking the simcard, by a small piece of software or by a cooked ROM? I'm hoping on the XDA community to give some insights into a possible solution.
Any news about this? A lot of people in The Netherlands have the same problem (Telfort on KPN!)

[Q] How do I use my Vibrant for gps and wifi while avoiding roaming related charges when in Canada or another country?
[A] this is the question I asked support at t-mobile. I got 2 answers, neither were completely correct. The problem is that you cannot block IMs and phone calls from reaching your mobile unless you go into airplane mode. (Note that you will receive charges for IMs and for calls you do not pick up as long as they register on your phone. This is what I was told by one rep. Other reo said that I should not be able to receive these since my account was not set up for international services, but as msgs and calls came in, I got worried.)
The short of it is this: for $20, I bought CoPilot off the android market and downloaded the North America maps. This app does not require data connection, and it works remarkably well. I then put the phone into air plane mode. After doing this, I enabled gps and wifi. This allowed me block all direct calls and IMs while retaining the ability the ability to use the phone for gps and for browsing when there was an available wifi network. (having a google voice account actual enabled me to send IMs when connected to a wifi network.)
It all worked so well, I am further considering dropping my data plan altogether since the places I typically use the internet are places with wifi (though perhaps I will wait until the 2.2 update is pushed.)

In terms of GPS, you are correct, you would have to purchase a third party GPS app for that (since google maps doesn't cache. Well it does, but if you find yourself lost after choosing a route and don't have wifi available then you are forced to turn on data so it can redownload your route, since it only caches your route and nearby streets.) To block incoming phone calls you just set up unconditional call forwarding (**21*18056377243# send) which will forward all of your calls to VoiceMail. The 1805 number can be replaced with your VM provider of choice (ie Google voice.) To undo, just dial ##21# and send. After that just disable data roaming and you are good.
In terms of stopping IM/SMS/MMS, just have care add message blocking (or better yet, go to your tmobile account and add it from there) its a free service that blocks all incoming or outgoing sms/mms/email as sms/IM. Sometimes the reps will just add the sms/mms block so you might want to add it yourself from the site.
Also if you purchased the vibrant on a contract then you can't remove your data.

Or if you want to keep the FULL functionality of your phone while traveling internationally you could buy a prepaid SIM for a carrier in the country you're visiting.

this ^^
If you did not want to get a SIM, you could just take your t-mo sim out. This way you could still use wifi, then use Google voice for texts and VM.
Is this possible? I'm currently overseas and using a third-party SIM card. The Wifi Calling app has a block on it that prevents you from using a third party SIM, but is there actually a reason why it WOULDN'T work if we could find a way to get around TMOs block? Maybe someone could mod the application?
What do you think???
I think it's likely that other companies don't support UMA calling, which means it wouldn't work. I haven't actually seen many cell providers that let you do Wifi calls. The app is probably hard coded with T-Mobiles information, so even somehow getting rid of the block wouldn't help you, as it would still try to connect through T-Mobile.
Hi so I recently activated the unlimited free text and calling from textnow on my samsung galaxy s8+ unlocked sm-g955u on their sprint network. When I had first done it I realized I was able to use free high speed data throughout much of my device with the exception of some games and apps it wouldnt work on.
So I set out trying to find away to bypass restrictions and limitations of the free data I had. I couldnt figure it out in the least, I tried everything I knew to hide usage. And in the process something horrible happened, I lost all that free data on everything except for the google search bar app. In which the google search bar you can search anything you want and all the results come up super fast. The catch is, I can no longer click any links and load pages beyond it. It just sits on a white blank page after clicking a link.
I tried to figure out what I did to change it or put their (I'm assuming) normal restrictions of data usage back in place where it was meant to be from the beginning. I havent been able to unlock the data since.. I e tried vpn like psiphon pro that I could use to get free high speed unlimited data from any captive portal login. But it doesnt work, rather textnow refuses to connect. Any sort of vpn textnow seemingly rejects the connection and I cant even place texts or calls.
I know textnow uses the sprint lte data service for its software. I know there is what I would call high speed lte data associated with my activated sim for text now. I can tell just simply by the load speeds of the google search bar reguardless of what you search for. That and what I had experienced when I first activated my sim and device.
So I'm coming here for a little help in brainstorming how myself and many other people who activated their own unlocked device in the talk and text plan, can bypass the restrictions textnow places on where the data can be used at. The data now is restricted to just textnow and google search (also nessecary functional apps) I know there is a way to hide this use of data, I tried the captive portal login which is speedy, but on pie i cant open the login into a browser to spread the service and i cant find a way to use the portal login to search anywhere else but textnow webpage.
Any ideas people? I'm sure many many people would benefit greatly to a loophole if any were found, and there is a loophole because my device was at first capable of near unrestricted data access before i tried to fully unlock it. If you know someone that might have some valuable input please tell them about this discussion and bring them here.

I realize this post is from last year, but I just ran across it and wanted to give my input in the event it may help somebody. As most TextNow subscribers are aware, T-Mobile's prior acquisition of the Sprint network is now geared towards shutting down the Sprint 3G & 4G networks nationwide. In fact, the lights have already went out on the former, while the 4G side is slated for complete shutdown by mid-2022. Accordingly, TextNow is presently migrating all subscribers over to T-Mobile's GSM 4G-LTE/5G nationwide network. Subscribers who were already using Sprint compatible devices are receiving free upgraded GSM SIM cards from TextNow to make the transition seamless. Unfortunately, this will likely be the end of all the free high speed 4G-LTE data subscribers enjoyed while connected to Sprint's network. This free data exploit was due to a proxy anomaly caused by the default reverse tunneling settings of certain brands and models of smartphones. While the knowledge will do little good now, the "restrictions" of using the data device-wide, across all apps and services, could be bypassed by setting up pdaNET+ on the TextNow device as host access point. Then, by enabling a WiFi direct hotspot via local proxy, the connection could be shared by a Windows 10/11 PC or laptop, by way of the pdaNET+ client-side setup. Then, by using the native Windows 10/11 hotspot feature, the data connection could be resolved and shared by other mobile devices in a normal device-wide manner. So while the TextNow host device would be unable to use the data across all apps and services, any devices connected to the Windows hotspot would have unfettered and unrestricted use of the data. Depending on how tech-savvy you wanted to be, the Windows PC Ethernet port could be used to traffic the data into a home router or extender for expanded sharing. Great while it lasted. I just recently received my TextNow GSM SIM in the mail, and haven't yet had time to experiment with data connectivity or exploits thereof. I will keep my findings posted here as I probe the uncharted waters .
So as you might or might not know, there already is a pseudo free data that is running on the google servers. Example: open a browser and search through google and you will get the results, its slow so I'm assuming its 3g. but they have a firewall that is blocking every other site unless its running via google servers.
You could theoretically setup a google hosted server yourself, maybe rent a cloud server out from google and run programs through there. run a tunnel through that for unlimited data on the phone. Someone just has to figure out how to do that.
For anyone reading this and wondering what we're talking about. Textnow is a free phone app you can use with their SIM/network and never pay a dime for phone service and texting, including media texting. It's totally free.
If this were to be more useful in terms of what sites we could visit, it would be a lot more lucrative.
Another idea I had, if someone has a pentesting rig that can run this network and see which ip addresses are being blocked, we could start building a list of sites that are whitelisted, both IP's and hostname resolved (http/s for example) this would allow us to see where we can start digging to find a place to setup a tunnel here.
I know that google has server hosting via their cloud computing network, you can even host DHCP style servers on it, so you could theoretically use this to tunnel through if the google server IP range is whitelisted. which it might be..
Google has an VPN that's free with Fi, so maybe you can pay for the VPN if you don't use Fi, therefore it's going through Google servers to then the user, so maybe if it costs less than TN's 1GB plan, we could consider it if it works.
