Customer Reviews / AT&T Single SIM Card UMTS 3G UICC-B (Version B)
Amazon sent me this entirely at random when I purchased a Sprint EVDO data card. It's utterly useless to me. I don't own a GSM phone and wouldn't use AT&T if I did.
I think I'll be buying all my future phones from Amazon, the prices are amazing and worth not having the "instant" gratification I used to get when I walked into a store and walked out with a phone.
The phone itself sucks but the SIM card got the job done. I was in Europe visiting from the US and the phone picked up all networks without any problems.
Yeah it's a sim card and well my phone doesn't have 3G so I don't really care that it works with 3G because it doesn't matter.
I don't know why they want reviews on sim cards. I find SIM cards outdated though, They are massive compared to Micro SD cards and yet they hold next to no information when compared.
The only reason SIM cards are good is because they go in GSM phones and if you unlock your phone you can cart it off to another service provider without issue. Especially quad band phones.
you get a new sim with your plan upgrade so its a technical thing...nothing complicated but useful because ur new sim will be of the latest technology and u can easily transfer your contact and information from your old sim to new sim and then call AT&T for activating your sim card
