No, it will not be possible to take 2G (EDGE) / 3G package in parallel.
Definitely all smart phones are compatible with 3G network but every smart phone, despite being expensive, may not support all features of 3G. 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. Theoretically, all 3G enabled smart devices should support voice & data with different speed level. But all handsets do not support default video telephony service. However, applications like Skype can remedy such limitations.
How I will understand that my handset is 3G compatible?
When you are in a GP 3G network area & if your handset shows “3G” or “H” on the top of the screen next to the network signal bars, it means that your phone is 3G compatible and you can use the 3G services. You also must ensure that the phone settings are not set to ‘2G only’. There are 2 types of handsets – WCDMA (R99) & HSPA. WCDMA or R99 devices are 3G devices but support low 3G speeds. HSPA devices are high speed devices & support any speed from 3.6mbps to 7.2mbps depending on the device. We recommend you to upgrade the handset from WCDMA to HSPA for better speeds & experience.
Do I need to configure any special settings on my phone to use 3G?
No, you do not need any additional settings to use 3G on your phone. However, you have to ensure that you are latched on to 3G network once the 3G service is activated. For this you need to select network mode to UMTS/WCDMA.
Do I need a specific type of handset for making a video call or I can use my existing 3G compatible device?
In order to make a video call, it is necessary to have a handset /device which supports video calling. However, using some applications (which are free & downloadable) will allow you to perform video call related activities (use of such applications also depends on device & OS type), even if direct video calling feature is not available in your handset.
Can I make a video call while using other operator network while roaming?
Yes, you can use all 3G services seamlessly while roaming on other operator network if we have a roaming tie-up with that particular operator & therefore you can even make video calls.
Is it necessary for both the parties to have a 3G phone & service to be able to make & receive video calls?
Yes, it is necessary for both the parties to have a 3G phone with video calling capability & they need to be connected on 3G network to make and receive video calls.
Can I connect my handset to my PC or laptop to use 3G services & access internet for faster speed?
Connecting a handset to laptop or PC is called tethering and this is definitely possible on GP 3G network if customer’s device allows/supports tethering. The charges will be applicable as per the subscribed tariff plan.
If I need a new 3G phone then do I need to purchase it only from GP or any open market handset will also work fine?
It is not necessary to purchase a 3G device only from GP; you can buy one from the open handset market but you have to ensure that it is 3G compatible for using 3G services.
How would I know whether my handset is 3G compatible or not?
When you are in a GP 3G network area & if your handset shows 3G /H/H+ (based on coverage type) on the top of the screen next to the network signal bars it means that your phone is 3G compatible & you can use the 3G services. You must also ensure that the phone settings are not set to ‘2G only’ ; alternately you can also check on the handset manufacturer’s website or the device box. Moreover, you can check the 3G compatibility of your devices from 3G Coverage Map under 3G section. 3G locations will be regularly updated there after expanding 3G coverage in any new area(s).
Will 3G network coverage be available across the country?
Depending on the political and other factors, GP will expand the 3G coverage across the country in phase by phase.
How I can get access to 3G services being outside of the 3G coverage area?
You can access 3G services while staying only in 3G coverage area. When you are out of the 3G coverage area, you enjoy browsing in 2G/EDGE speed.
How can I connect to GP 3G network?
As a first time 3G user you will have to follow the following steps to connect to GP 3G network:
Firstly, speed depends on handset, coverage, network traffic and number of users currently using the 3G network at a particular point of time. Secondly, it depends on customer’s subscribed Data Package Speed. GP will be offering Data Packages of different speed tiers. Such as - 1) 512Kbps and 2) 1Mbps
How do I test my speed or ensure 3G experience?
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.
What is HSPA+ and what are its benefits?
With 10 MHz spectrum and network readiness Grameenphone is the only private operator who can launch 3.9G or HSPA+. This will ensure better user experience while using 3G network.
Why GP is using “3.9G HSPA+” technology for its customers which is not offered by other competitors in the market?
Grameenphone is building a 3G network that will ensure ample capacity and superior customer experience. Based on customers’ handset capability Grameenphone network will support basic 3G, HSPA (3.5G), Dual Carrier HSPA or HSPA+ (3.9G). With 10 MHz spectrum and network readiness Grameenphone is the only private operator who can launch 3.9G or HSPA+. This will ensure better user experience for GP customers while using GP’s 3G network.
What does it mean by E, 3G and H or 3.5G as network symbol on Mobile phones?
H or 3.5 G stands for HSPA (High Speed Packet Access). HSPA 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.
If it is possible to avail 14.4Mbps download speed per user with HSPA & 2 Mbps per user with WCDMA in good coverage and quality conditions (mentioned in the answer against Q9), then why Grameenphone’s 3G packages have a maximum speed of just 1 Mbps?
Grameenphone is aiming to ensure to consistent data speed around the committed level all over the network, and to do so a speed level that is required by majority of the users is being implemented.
What is the difference between 3G and Wi MAX?
The Wi MAX 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 Wi MAX 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.
Can I make a video call to other operator’s customer having a 3G phone connected on a 3G network?
Yes, you can make a video call in such a situation where network can be of any other operator if we have interconnectivity agreements with the operator.
Does 3G improve the voice quality automatically?
No, the voice quality is the same in 2G and 3G. It brings additional capacity to further support peak hour voice usage.
What happens when I move from 3G to 2G network?
When you move from 3G to 2G network then all the service supported on GP 3G network like video call, high speed internet access, etc will not be available. Rather you will get basic service like what you get now under 2G network. If you were on a voice call while moving from 3G to 2G network, the call will continue without any interruption.
I have not subscribed to GP 3G services, yet my phone is showing 3G. Why?
Your handset will display the 3G/3.5G symbol in areas where the service is available. But 3G plans do not get auto-activated and must be subscribed to use the services. To subscribe, you have to send SMS to 5000 typing 3G.
I experience good 3G reception during day time, but I can see only 2G during busy hours, why is it?
When number of users is getting increased, tower drops down its coverage radius to give good QoS to users, because of that some customers may get out of 3G coverage during busy hours.
