under water telecommunication and is uses?

Are you refering to communication to submarines.\n\nCheck out the ELF project, extremely low frequency telecommunications.

Very unfortunate indeed. Theres nothing u can do, unless you have a ton of money to set up the telecom infrastructure. Have you checked with all providers who provide landline phones in your area? Have you checked if Cable internet is available?

Use another satellite phone.

Find or build a jammer for frequencys above 820 and below 900mhz. Set the jammer to where the calls are made. Have a antenna wire run throughout the area. Good luck.

It's an old fashioned kind of modem, common in the 70s and early 80s, which was connected to a phone by placing the phone handset onto the unit, which had a cradle to hold it and two rubber cups for the earpiece and microphone.  Data was sent via audio signals through the handset.  \n\nNeedless to say, data was sent much slower than we're used to today.  Top speed was, IIRC, about 300 baud.

Telecommunications is the science and technology of communications at a distance by electronic transmission of impulses, such as by telegraph, telephone, radio or television. It is the foundation for the Internet and all of the emerging activities surrounding the Internet's activities. Telecommunications is the transmission of information by wire, radio, optical cable, electromagnetic, or other means.

THAT DEPENDS ON WHAT YOU WISH TO COMMUNICATE. THRY HAVE GREAT UNDERWATER SENSES AND CAN RECEIVE STIMULI FROM A NUMBER OF DIFFERENT SOURCES.\nSMALL ELEC. CURRENT\nPRESSURE WAVES DUE TO WATER CURRENT\nLOW FREQ. SOUND WAVES\nSIGHT\nOLFACTION [SMELL]

it could be possible to use an satellite internet service provider from anywhere on the globe without filtering.  though you would have to have a satellite dish installed to recieve the signals.\n\nthe filtering occurs at the ISP level so if you cant get to a different provider, you have little chance of defeating the filtering without HEAVY coding/hacking.

It can't really. The key here is 'information' and information is different from data. The thing is that the data you are sending doesn't contain as much information as you think it does. In other words it can be compressed. So the data you can cram down a phone line is first compressed and then sent in a way that makes the absolute best possible use of the available bandwidth. \n\nit's not worth going into the details of the modulation techniques, in the end they all require a small change in the signal to pass a bit of compressed data and that requires bandwidth. There's no magic in this, just clever physics and software.\n\n(n2thepowerofn below) Lol!

There are plenty of companies working on ways to make this type of service available, most likely through the use of bluetooth or some other technology (certainly NOT through text due to lack of security).\n\nThere are no currently viable options to use this today however.

You need something called Call Wave.\n\nIt is available at the following site:\n\nhttp://www.callwave.com\n\nYou will also need to subscribe through your phone company to "call forward when busy".  Then when somebody calls you, it is forwarded to Call Wave, and they record the message as a WAV file.  That file is then sent to you and played so you know what you missed.\n\nThe service is free, and really easy to use.  It saved me many times before I got high speed.

Water + Electricity = Bad News\n\nSealing electronics and connectors is difficult and expensive.

Currently the world's communication systems are dependent upon the Trans-Pacific and the Trans-Atlantic Fiber optic cables.  Satellite traffic does not carry near as much information as these two cables.
