Verizon does not use sim cards in their phones (except the iPhone). So no you would not be able to use an AT&T Sim card in a new Verizon phone. sorry.
no they have to be phones strictly made for at&t and the sim cards could be shaped differently and get stuck.
yes
iphone and a ipod touch
Because Boost does not use a GSM network, they use iDEN. Boost phones use a SIM card that is compatible with GSM phones for overseas roaming. However, iDEN is a very different standard from GSM. Most iDEN phones are not compatible with GSM networks, and GSM phones are not compatible with iDEN networks.
usually card readers aren't compatable with blue tooth phones. typically you will have to get one that plugs in instead of a wireless handheld card reader
none verion uses cdma and rest use gsm tech.
Not all cell phones are compatible with SIM cards. Some only work with a contract, and you need to unlock the phone before you can use a SIM card.
Nokia, Motorola, and Samsung all have phones available which are compatible for use with a Sony Ericsson memory card, according to consumer reviews. One who wishes to use Sony accessories with other phones, however, would be well-advised to confirm the size of the memory card and be aware of different storage capacities among different memory cards--even when they are produced by the same manufacturer.
There are many cell phones that has a sim card. Mostly, all cell phones come with a sim card because most of them are prepaid phones. Trac Fone, Verizon and there are many other phones that have a sim card.
Metro PCs is able to "flash" phones from other carriers for use with their service under certain conditions. The phones must be CDMA, meaning they do not use a SIM Card (Major CDMA carriers include Sprint, Verizon, Qwest, Cricket, Alltel). You will not be able to access all features of the service when using a flashed phone, these phones are good for calls and texting only. The phone does not be unlocked to be flashed.
The short answer is no. Boost's newer iDEN phones do use a SIM card that can be used in GSM devices for international roaming but they will not work in GSM devices in the US. Most iDEN phones are not compatible with GSM networks, and GSM phones are not compatible with iDEN networks.
Right now you can get the iPhone through AT&T and T-Mobile. All you do is order a sim card and you can use T-Mobile on your iPhone. WHen it will be able through other carriers some people say will be in January when the iPhone goes to Verizon, and October when it goes to Sprint.
Well...As of April 2011 the American iPhone is compatible with:AT&TVerizon WirelessSprintC SpirenTelos**can also use T-Mobile's slower EDGE network with a SIM Card for those who are desparate to own these quality devices.***Once again, these are only the American carriers.
Virgin Mobile now uses sim cards and ATT and other carriers only what customers to use their phones, so the phones are locked for use only on their network. If you get an unlocked cell phone you can use it on any carrier that uses sim cards. NOTE: Tmobile and prepaid carriers don't have Iphones on the service.
