yes they have the same Cdma Network
Generally speaking, one cannot switch a T-Mobile phone to the Sprint network. This is because T-Mobile uses the GSM standard, while Sprint uses the CDMA standard, the two of which are not compatible.
A defective product has a defect: "My phone is defective" "What defect does it have?" "The defect is that the screen is broken" To defect can also mean to switch sides e.g. from an army or a political party
SIM (Subscriber Idendity Module) is the only idendity of Service Provder on your mobile handset. It means all the credentials and secrect Keys related to network Authrization are stored in SIM card. When mobile is booted up first thing it will do is to search the Network, The network name is stored in the SIM. When it finds the network then mobile will attempt to authorize on this network using Secret keys stored in the SIM. Without SIM mobile phone doesnt know anything about Secret keys so it cannot camp on to the network without SIM.
Since IMEInumber is unique, it will help us in locating your lost or stolen mobile handset. For now, note down this IMEI number and keep in a safe place. You can also find your mobile IMEI number on your mobile handset packet cover.When you switch on our mobile phone, your mobile SIM card tries to connect with any available network. Once it finds a supported network it tries to build a network connection between your mobile handset and the nearest tower. During this connection negotiation, your SIM transfers some internal information to the network operator such as your mobile IMEI number, mobile model, version etc. This means your mobile operator keeps the record of your mobile handset number each time you try to switch on your mobile handset and use their service.Now if you have lost your mobile handset or your phone has been stolen, you can contact your network provider to block your IMEI number. They might ask you to get a Police FIR copy first, do as they say and finally ask them to block your IMEI number. Mobile network providers use a shared hosting service for blocking IMEI numbers, which means if you have asked network 'Airtel' to block your mobile handset, it automatically gets blocked by network 'VodaFone', 'Reliance', 'Idea Cellular' and so on.Now when that thief will switch on your mobile handset, no service providers will allow it to build any connection with them. It does not matter if he changes the mobile SIM card, since SIM card requests for the service with IMEI number and a blocked IMEI number handset will be ignored and the mobile will become an useless toy.
You can use either a network hub or a network switch to set up your network
Yes, switch as well as hub and router are network devices.
it is a switch in hubs
under settings switch to auto instead of T-Mobile. It worked for me, and I'm running 2.1 firmware, unlocked and jail-broken!
Every time you switch on your mobile, It automatically sends out a piece of RFID (or 'find me') data. This is picked up by the nearest phone masts, so the network can route calls texts and data to the handset.
A managed switch is a network switch, which is used for connecting computers and network devices. It is handy because it allows you to handle individual ports of the switch.
