    Can anybody confirm this?

    I just had a buddy call me and tell me to remove the SIM card from my Tour. He said that he was told that even if you have the network setting on 1XEV only, and if the SIM card was inserted it would still try to look for a GSM signal in the background when the CDMA signal got weak. I guess because of this the battery life is greatly reduced. He also said to dial *22899 to update your PRL after SIM is removed. Now he claims that after he did this he has better signal strength, and is able to make calls in places he was never able to before. Has anybody else heard of this, or does it even sound like it could be plausible? I would guess in theory it would work on Verizon Storms as well, because they also have SIM's.


    No matter where you go, there you are

    I have read that before as well and always take my SIM out. I think it makes sense, as every time I rebooted with SIM in, it constantly asked for network. Unless you plan on traveling outside US or need to use a SIM from a different carrier, I would also recommend taking your SIM card out.

    I had the problem when I was set to global with the SIM in.

    I took it out and set it to 1XEV and was good to go. So, you should be cool.

    Yeah it makes sense, but would it really give you that big of boost in battery life and signal strength?

    I am sure it wont significantly make an impact, but will give you that extra boost that sometimes all us wish was there. With storm 2, the battery life is not the best, so anything is worth trying, whether it proves to be true or false.

    Honestly no, I forget exactly the issue now cause it's almost a year since I took the advise from my brother. I believe it was connection, possibly the signal. I'm sorry I can't remember. I will ask him in the later morning and get back to you.
    As far as battery life no, I have the original and have been good since the start

    Thanks Neo, and Olta. I would really be curious to hear what he says Neo. I dont know if its just wishful thinking, but my battery life does seem to have got significantly better. I took it off the charger at around 10 or so, and it's now 0500, and I have 89% still.

    I just removed my sim card to try it out as well. I'm curious to see if I will have a better connection in my neighborhood.

    Nice, I never knew this.... I would think this only drains on your battery more if you have no CDMA signal and its not set to 1XEV only in mobile connection....PRL updating is well known to most I believe.

    Not to be a nay sayer but there is no GSM in the US for VZW. Their technology is based on CDMA. The only time the SIM card comes into play is when you are overseas. So removing the card, changing the settings on your mobile network is superfluous while in the US with respect to battery life.
