Question

What is the moble network when u can call all the networks?

Answer 1

To explain this first of all there are two types of Wireless technologies GSM (Cingular, Tmobile) and CDMA (Verizon Wireless, Sprint, Alltell). GSM companies can only recieve GSM and CDMA companies can only use CDMA Signals.

There are other companies like virgin mobile, ampd, helio, qwest are called MVNO which mainly means that they pay Verizons, sprint, or Cingulars network to do business for their customers.

Most large networks currently share each others networks, thats where you hear about "Extended Network" from Sprint, Verizon, Alltel share some of each others networks but not all of it. And Cingular and Tmobile share each others networks too but not all of it.

Here's something to look into though, currently Helio is using the sprints network for their customers but they are in talks with Verizon Wireless to use their network as well, if Helio is successful Helio would have the 2 strongest networks to use even though they don't have their own network. Currently Cingular, Sprint and Verizon has the largest Networks.

Cingular, Sprint, Alltel, and Verizon will all say to you they have the largest network, really those companies have large networks but how they justify it is by if you combine both their home network and extended networks they have the largest network but those companies will never admit who really has the largest network but only themselves when they are selling their product.

My suggestion of networks would be to go with Sprint even though they have the largest extended network but your phone will be used in more places, but their customer service is poor. Cingular and verizon has a very large of their own network and their customer service is ok and Tmobile has a smaller network but they have excellent customer service but poor selection of phones.

If you have any questions about phone service or advise come talk to me I used to work for Verizon Wireless but I have done lots of Wireless study from all companies and I can help you find the right service provider for you. my email is [e-mail]
