Hi,
I live in India and the biggest network provider here 'Airtel' has started charging insane data charges on VOIP calls. I want to know if there are ways to hide VOIP data packets and mask them as regular data packets? Will VPN(any free/affordable options?) help or they can still detect VOIP packets through deep packet inspection?

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...

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.
[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.
Hello,
are you familiar with an application where i can use my home telephone line (connected to modem on desktop machine) to place phone calls from my android device (through wifi)?
Thanks.
you need a piece of hardware to connect the landline to your internet router and convert PSTN signals to Voip and viceversa.
Such hardware's name is voip gateway and i have seen them for 70$
(like linksys spa 3102)
that piece of hardware would translate between internet Voip traffic / landline voice and would pickup calls / make calls / forward calls according to configurable rules. It would have an interface to configure the device using a local ip adress like 192.168.1.10 and there you would have dozens of options for doing everything you can imagine. Then you can use any voip / SIP software you like to place and receive calls, even on your sip client of your mobile phone.
With this i would have the power to make calls to landline in my country for free, using the data connection of my mobile phone to "talk to the router of my home" and voipGateway would place a call for me to any landline destination (which is free landline to landline) and divert the voice.
You need:
Internet router connected to landline (normal dsl service)
Voip gateway connected to both landline and the internet router
A phone company who let you make free calls from landline to landline
There are some routers which have all of this integrated, and have voip support and 2 rj45 jacks, for the connection to the DSL and Landline
please how do i enable cell broadcast on this phone? i cant seem to locate the feature anywhere.
i need it because my home network gives good discounts on cell broadcast for calls
Hi to all, i have a question about architecture of android OS, and i would have an answer before i start develop my custom android OS.
I would like to know wich "component" of android OS take decision about which network interface use for sending and receive data. As we know, if our system has a 4g network active and is connected to a wifi network too, all network data goes through wifi connection.
I would like to know which is the portion of os that "take" this decision, and if is possible to modify it for manage network connections and traffic forwarding in different way as default (for example send automatically an email with 3g network also if a wifi network is active).
