Hi there. it could be one of a few problems, firstly, check if you have a 3G phone? secondly, check if you have 3G coverage? Thirdly, do you have a 3G sim card? If this doesn't answer your question, you should go to a service provider shop so that they can check it for you!

How do start my 3g services by using gsm


GSM phones use SIM cards, so you will need to pick a service provider (AT&T, T-Mobile, Simple, etc) first. Obtain a SIM card from them, insert it into your phone, and your service will begin. If 3g service is not working, it could be your physical location, which would affect signal quality. Check your phone settings as well to make sure data is enabled / available.

How to turn on 3G network on Samsung galaxy s2?


Settings > More Setting > Network Settings > Mobile Networks > Network Mode > WCDMA Only or WCDMA/GSM (auto connect)

WCDMA Only is is you only want to use 3G.
If you want that your phone should switch between 2G and 3G mode automatically, use auto connect option.

For this, your SIM Must support 3G services.

I have sciphone i68 but it does not work on 3g sim card what i should do?


You need to get a non-3g sim card, or get a 3g phone. Only the very latest Chinese mobile phones are 3g compliant, as China (apparently) does not have a 3g network as yet. Unfortunatley you can't modify the sim card or the phone to fix this problem.

Network problem


Hi,
For information about the Motorola RAZR V3x and what carriers it will be on, here is a quick answer: only GSM carriers. For those unaware of the technology behind cell phones, there are two major competing technologies GSM and CDMA. You will never be able to use a GSM phone on a CDMA network or a CDMA phone on a GSM network.If it's all ok for you then call upon your service center.
Hope this Helped!

I68+ Not registering on O2 Irl Network


After further research into the phone, I have discovered that it does not support any 3G network and as vodafone and O2 in Ireland are now 3G networks, neither the I9 or the I68+ will work on these networks. They only support 2G networks(GSM). Will work with Meteor Irl but this network is in the process of changing to 3G so these chinese phones will soon be useless in the Republic of Ireland.

In the NEWORK menu, change the network mode to either of the following:-

GSM 900/1800: the phone operates in the
combined GSM 900/1800 network.

GSM 1900: the phone operates in the GSM
1900 network. This option is only available in
USA.

This should turn of 3G functionality but expect that you will have less reception too

3G HSDPA


3G is the 3rd Generation of mobile phone standards. It superseeds 2G (GSM). GSM is the most used standard in older phones. Your phone supports 2G and 3G. 3G offers a greater mobile network capacity and more advanced mobile services.

HSDPA (High Speed Downlink Packet Access) is a data transmission available for 3G networks. Theoretically it can achieve theoretical data transmission speeds up to 15 Mbps. Most services offer 2-4 Mbps at the moment. It can be used for downloading.

For more information, you could look here for 3G and here for HSDPA.
