LTE 4G= SIM Cards
I was wondering if this LTE 4G will mean that VZW will have SIM cards for all their phones? That is the main thing I like about att (but not their coverage) that I can easily switch between phones 🙂 Thanks
Also- How is everyone liking the new Tour?

CDMA carriers COULD support R-UIM (Removable User Identity Module) which is a smart card the size of a postage stamp, very similar to a SIM card in GSM. It allows a subscriber to easily switch between phones and keep all of their phonebook and subscriber data (phone number, features etc). If the R-UIM module is inserted into a GSM device, it will function as a regular SIM card, allowing CDMA subscribers to roam to GSM very easily (of course the CDMA carrier will have to have a roaming agreement with the GSM operator). Verizon and Sprint choose not to support R-UIM. So if Verizon isn't supporting R-UIM there is no reason to believe they will do anything differently when they migrate to LTE.

I do not know that they will or will not. Read my post. I am merely pointing out that Verizon could support R-UIM cards on CDMA if they were concerned with customers having the ability to switch phones easily. They have chosen not to do so. The Device Change option (*228 Option 3) often fails. It is conceivable that VZW will switch to LTE and not support SIM cards at all based on their history.

If it happens sounds good to me. Reading that article it sounds as though this will only allow SIM swaps from one Verizon device to another Verizon device. We still do not know how they plan to execute voice. Will they use VoIP? Will they use LTE only for data and continue using CDMA? I believe it will be the latter. That way they won't have to worry about paying roaming revenue to AT&T (assuming AT&T ever gets their LTE network online). With Verizon's HUGE network (now that they have Alltel) why would they wish to give up that advantage?

If you put a Verizon SIM card in a LTE device, you will only get data which is all that LTE is. LTE is strong enough to support VoIP tho, so if you have a google voice app or skype it will work. Verizon is using 1X for voice to keep strain off the network until it gets 100% deployed. We won't need to pay AT&T roaming charges because our network will cover all the US except Alaska.

Wonderful. Sounds like you have it all figured out. As I said previously, I do not know. We will see what happens. I will believe it when I see it, however. I certainly do not believe they are going to make it easy for a rival's device to operate on their network. History does not show them to be willing to do so. I am still awaiting the Open Network. It would be nice.

#1. VZW will use a SIM-like card for all their LTE/4G devices- but don't expect to see LTE SIM slots in any 2G/3G devices- ever. Those will continue to support only GSM SIMs for global 2G/3G roaming purposes.
#2. The Open Device Initiative is a joke (from a consumer standpoint). The ODI program certification standards basically allow for two types of devices: 2G only phones and machine-2-machine diagnostic tools like remote meter readers for power and water companies or GPS trackers going into ankle bracelets for felons on parole. If you don't believe me, go to their website and read all the certification documentation. I have.
Even though every Sprint handset is authorized and deemed technically sound enough to roam on the VZW ...

I posted on this in May after receiving the official press release from Verizon. Follow the link and read both posts.

Basically, the answer is yes, but they won't be called SIM cards.

Any idea on the execution? Will LTE simply replace EV-DO? Will they continue to use 1x for voice or will their be VoIP or VoLGA? I look forward to the coming years to see how LTE and WiMax are implemented by the carriers.

I don't know how things will progress. I haven't seen any specific information.
I DO know that LTE will seamlessly handshake back and forth 1X data as well as with most current GSM data technologies, but would work entirely differently from standard voice technologies. This means a data connection should have no trouble flipping between old and new formats.
LTE for voice is a very strong possibility in the future, but given the extensive 1X network already in place - the bread and butter of the Verizon voice network - and the amount of handsets already in the field that work on that tried and true network, I don't believe it will be going away for many years.
