I was about 600 miles from home last weekend. My storms battery only last about a day when away from home service area and about two days,with moderate use, when in home service area. Will unlocking the storm allow the battery to last as long away from home as if it were in the home service area?
Unlocking your storm would give you the option of using it on a gsm network with a gsm sim card. So I would say no it wouldn't help with roaming because you would still be on Verizon's network even with a different sim because I believe you would need to have an account with say TMO or ATT to get the data and such with their sim cards.
