You know that it is very expensive to make a call to India from UK by using our own mobile network. It would cost around 1 to 2 pounds ( Rs.80 to Rs.160) per minute to make calls to India. And you may be charged upto Rs.100 to receive a call from India. So what is the solution? There is a solution for every problem.
The solution is to buy an international SIM card online which costs from £6 - £20 (Rs.480 to Rs.1600) which allows you to make cheaper calls and also receive calls on your own mobile from any where. These kind of SIM cards can be used in any mobile phone on either pay as you go or contract as long as your mobile is unlocked to use on all the networks.
There are a number of International SIM cards which give you cheaper international roaming rates for hundreds of countries world wide including free incoming calls.

How to back up address book of Mobile Phone online
Cell phones have now become a part of our daily lives and many of us can’t imagine what we would do without one. But the most important thing about a cell phone is the information stored in it. Do you use your cell phone SIM card to store the important contact numbers of your friends, family and business contacts and more..
Most cellular companies nowadays offer backup services for a nominal fee while many new cell phones can transfer and sync contact data to your computer through USB cable, Bluetooth or external memory cards.
We are now going to look at a web based service called Zyb that allows you to backup all your mobile phone numbers online. Zyb is an international mobile phone backup service and chances are fairly high that it supports your phone model and your phone operator. Zyb service backs up and syncs your cell phone’s contacts and calendar data so that you’ll never have to go through the pain of manually entering in contacts on a new phone again.
How does it work?
The process is fairly simple and quick, I received the code and the setting within one minute. You create an account on Zyb website by typing your phone number, selecting your phone model and your cellular operator. You will soon receive an SMS confirmation code and you’re all set to store your mobile content on Zyb website.

Difference between GSM and CDMA
. GSM (Global System for Mobile Communications).....GSM is the “branded” term referring to a particular use of TDMA (Time-Division Multiple Access) technology. GSM is the dominant technology used around the globe and is available in more than 100 countries. It is the standard for communication for most of Asia and Europe. GSM operates on four separate frequencies: You’ll find the 900MHz and 1,800MHz bands in Europe and Asia and the 850MHz and 1,900MHz (sometimes referred to as 1.9GHz) bands in North America and Latin America. GSM allows for eight simultaneous calls on the same radio frequency and uses “narrowband” TDMA, the technology that enables digital transmissions between a mobile phone and a base station. With TDMA the frequency band is divided into multiple channels which are then stacked together into a single stream, hence the term narrowband. This technology allows several callers to share the same channel at the same time.
2. CDMA (Code Division Multiple Access).......CDMA takes an entirely different approach from GSM/TDMA. CDMA spreads data out over the channel after the channel is digitized. Multiple calls can then be overlaid on top of one another across the entire channel, with each assigned its own “sequence code” to keep the signal distinct. CDMA offers more efficient use of an analog transmission because it allows greater frequency reuse, as well as increasing battery life, improving the rate of dropped calls, and offering far greater security than GSM/TDMA. For this reason CDMA has strong support from experts who favor widespread development of CDMA networks across the globe. Currently, you will find CDMA mostly in the United States, Canada, and North and South Korea. (As an interesting aside, CDMA was actually invented for the military during World War II for field communications.)
3. The Main points of contention between TDMA and CDMA is as below:-
a. Data Transfer Speed:.....With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast "3G" standards, or 3rd generation technologies. EVDO, also known as CDMA2000, is CDMA's answer to the need for speed with a downstream rate of about 2 megabits per second, though some reports suggest real world speeds are closer to 300-700 kilobits per second (kbps). This is comparable to basic DSL. EVDO is in the process of being deployed. It is not available everywhere and requires a phone that is CDMA2000 ready. GSM's answer is EDGE (Enhanced Data Rates for GSM Evolution), which boasts data rates of up to 384 kbps with real world speeds reported closer to 70-140 kbps. With added technologies still in the works that include UMTS (Universal Mobile Telephone Standard) and HSDPA (High Speed Downlink Packet Access), speeds reportedly increase to about 275—380 kbps. This technology is also known as W-CDMA, but is incompatible with CDMA networks. An EDGE-ready phone is required.
b. Subscriber Identity Module (SIM) cards: ........In most of the countries only GSM phones use SIM cards. The removable SIM card allows phones to be instantly activated, interchanged, swapped out and upgraded, all without carrier intervention. The SIM itself is tied to the network, rather than the actual phone. Phones that are card-enabled can be used with any GSM carrier. The CDMA equivalent, a R-UIM card, is only available in parts of Asia . CDMA carriers require proprietary handsets that are linked to one carrier only and are not card-enabled. To upgrade a CDMA phone, the carrier must deactivate the old phone then activate the new one. The old phone becomes useless
c. Roaming: .......For the most part, both networks have fairly concentrated coverage in major cities and along major highways. GSM carriers, however, have roaming contracts with other GSM carriers, allowing wider coverage of more rural areas, generally speaking, often without roaming charges to the customer. CDMA networks may not cover rural areas as well as GSM carriers, and though they may contract with GSM cells for roaming in more rural areas, the charge to the customer will generally be significantly higher.
d. International Roaming:.......If you need to make calls to other countries, a GSM carrier can offer international roaming, as GSM networks dominate the world market. If you travel to other countries you can even use your GSM cell phone abroad

What is a Sim Card of a mobile phone?
SIM card is the card which contains the specific information of the user who use a GSM mobile. This card contains information that is used for billing purposes. Simply put, it is like an identity card for the user who uses a GSM mobile. SIM is the short form of Subscriber Identity Module and you can easily understand its function by reading its name.
The main function of a SIM card is to store information of different users . However, there are lots of benefits that are associated with SIM card and the best one is about the portability as you can easily use another mobile by changing the SIM card. So, the things are really getting even convenient with the introduction of SIM card. However, it is essential to mention that SIM card is not just a portable memory chip as it is an amazing piece of technology that can easily amaze anyone.
A SIM card is just like a hard disk in a computer. Like a hard disk, it also keeps specific data like messages, phone book and other such like information can also be found in SIM card. Also, it stores the International Mobile Subscriber Identity or simply service-subscriber key which is essential to recognize a subscriber. IMSI is used to recognize a user on their individual operator network, whereas, Integrated Circuit Card ID is used to recognize each SIM internationally.

Yes Your CELLPHONE Can Do this......
THINGS YOU NEVER KNEW YOUR CELLPHONE COULD DO...
Your mobile phone can actually be ur life saver or an emergency tool for survival
FIRST
Subject: Emergency
The Emergency Number worldwide for Mobile is 112. If you find yourself out of coverage area of your mobile network and there is an emergency, dial 112 and the mobile will search any existing network to establish the emergency number for you, and interestingly this number 112 can be dialled even if the keypad is locked. Try it out. I’ve tried it myself & it works in India.
SECOND
Subject: Have you locked your keys in the car? Does your car have remote keys?
This may come in handy someday. Good reason to own a cell phone:
If you lock your keys in the car and the spare keys are at home, call Someone at home on their cell phone from your cell phone. Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end. Your car will unlock. Saves someone from having to drive your keys to you. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other “remote” for your car, you can unlock the doors (or the trunk).
THIRD
Subject: Hidden Battery power
Imagine your cell battery is very low, you are expecting an important call and you don’t have a charger. Some Nokia instruments comes with a reserve battery. To activate, press the keys *3370# Your cell will restart with this reserve and the instrument will show a 50% increase in battery. This reserve will get charged when you charge your cell next time.
AND FINALLY...
FOURTH
Subject: How to disable a STOLEN mobile phone?
To check your Mobile phone’s IMEI serial number, key in the following digits on your phone: * # 0 6 #
A 15 digit code will appear on the screen. This number is unique to your handset. Write it down and keep it somewhere safe. When your phone get stolen, you can phone your service provider and give them this code. They will then be able to block your handset so even if the thief changes the SIM card, your phone will be totally useless.
