Frequently Asked Question
Human being always desires to live unbound. But our reality is totally different as we are living in a small developing country with ever growing population and amidst huge resource limitation. Our country - our "Real world" is increasingly running out of space, scope of making required infrastructures, being choked up with crowd and traffic. We are getting localized simply because of congestion in everywhere resulting in shorter effective life. Most of our fertile time of our only life is being wasted either in the long tailback of vehicles or being queued up or in some unproductive ways. In this way everybody is deprived of enjoying or utilizing his life on his own. If we were able to expand our real world we could have contained all the limitations substantially. But we are undone! Consequently our country is losing its huge potentiality and incurring environmental disaster everyday. Against the backdrop we can create a "Virtual world" that will exist hand in hand with the "Real world". We can continue virtual working ,wherever or whenever we require, with a smart device connected to 3G networks either in stationary or on the go environment. We can meet up some of our requirements by accomplishing official or professional works and get enough recreations in the process thanks to 3G. In this way we can make our life easier to some extent and have a manageable life. Apart from that an opportunity would be crafted to cash in hitherto untapped global IT market which will help us keep pace with the ever changing world.
The G in 3G network stands for "Generation" and 3G Network stands for the "Third Generation" of telecommunication hardware standards and general technology for mobile networking . In other words 3G is a family of standards for mobile telecommunications that include simultaneous use of wide-area wireless voice telephone, video calls, higher wireless data rates on cell phones and other Internet-enabled devices both in mobile and stationary environment.
According to the International Telecommunications Union, five technologies comprise 3G technology as a whole. These technologies include:
As 3G technology is a group of radio interfaces it offers wide-range of wireless network service and capacity. 3G technology provides subscribers with enhanced functionality, including larger bandwidth, faster data transfer rates and spectral efficiency .The 3G network is designed to support advanced capabilities contained in mobile and stationary communication devices. Smart-phones have been the main beneficiaries of 3G technology, but devices such as desktops, laptops and tablet computers are capable of using the technology as well.
Communication devices connected to the 3G network experience up to 14.4 megabits per second download speed and up to 5.8 Mbps upload speed.
Unlike second-generation, or 2G networking, 3G allows for the simultaneous transmission of voice and data due to its increased bandwidth.
To enjoy the benefits of 3G network coverage, three requirements must be met:
You can buy USIM and connection from any of your nearby Teletalk Customer Care Centers or retailer points of Dhaka listed in the Teletalk’s website, www.teletalk.com.bd whenever you want.
You will be continuing with 2G/2.5G services in areas where 3G coverage is absent. In that case you have to ensure that your network setting on handset is on dual mode(GSM/WCDMA Auto Mode).
You can access 3G services while roaming outside the home network if you have roaming facility and under an operator who has 3G Coverage and has roaming agreement with TBL.
3G will work on your existing 2G SIM card by switching to 3G packages. So you need not replace your existing SIM card. To switch to 3G just go to message option, type 3g and send to 666 with balance of at least Tk.500 in your account. Within 72 hours upgradation will be completed and you will be notified accordingly. If your mobile is not converted to 3G as mentioned, you may call to Teletalk helpline-121.
If you are first time user please follow the steps as given below to connect to Teletalk 3G network :-
Step-1: Get a USIM with connection/ Upgrade your existing SIM to 3G package.
Step-2: Select network mode to "Dual/WCDMA/3G/UMTS". For data usage dual option might be avoided.
Step-3: Configure your packet data settings with APN "wap" or type "set" and send to 738 to get a message which you need to save with password "1234" in your mobile.
Step-4: After registration, seeing 3G/3.5G/H network symbol on your device and enabling your device data transfer, instantly you may start enjoying 3G services.
Definitely a smart phone but every smart phone, despite being expensive, may not support all features. Because manufacturers are at their own discretion develop mobile stations with versatile features. Technically, R99 , HSPA and HSPA+ supported handsets are compatible with 3G network and will at least support the Voice Service. But, regarding availability of Data Services the availability varies with type of handsets. Teletalk has tested a number of renowned Mobile Stations presently available in the market which has been detailed in its website http://www.teletalk.com.bd.
3G has superseded 2G technology and precedes 4G technology. When compared to its predecessor, 3G network coverage offers several features and improvements that 2G coverage didn’t have, including high-speed Web browsing, three-dimensional gaming and a high level of security. Because of its backward compatibility, 3G networking can do all that 2G networking could, such as digital voice, voice mail, conference calling and simple data applications, like email. Because of 3G networking's ability to handle high-capacity data transfers, it supports features like Video conferencing and Mobile Television.
H or 3.5 G stands for HSPA (High Speed Packet Access) is a new generation communication protocol that allows data connections up to 14.4Mbps download speed and up to 5.8Mbps upload speed per user in good coverage and quality conditions. 3G means WCDMA (Wideband Code Division Multiple Access) that is a 3G technology version that allows data connections up to 2 Mbps per user in good coverage and quality conditions. E stands for Enhanced Data Rates for GSM Evolution, known as EDGE that is 2.5G technology version which can go up to a speed of 264 Kbps.
The WiMAX standard is used mostly only for transferring data although echo-system which supports voice using WiMAX technology is not available as of today at affordable price. A WiMAX network is more similar in function to a large, integrated Wi-Fi network although data handover facility is there.
With widely available echo-system a 3G network is designed for both voice and data traffic with availability of seamless service while an individual is in motion.
FLASH is nothing but a plug and play 3G modem to connect to the internet at very high speed. After inserting FLASH into the your devices, just dial 1515 from your device to activate the modem and enjoy like never before. For better performance “only 3G” should be opted in the network setting.
