    I activated the phone but when I tried to hook it up to straight talk it said the phone wasn't compatible. I know nothing about cell phones so i'm having a real problem getting this to work.

    Did you get an AT&T Straight Talk SIM?

    Laura is correct...

    You need an ATT compatible SIM from Straight Talk to make your 635 work. Or you have to get it unlocked from ATT by ATT.

    Greetings Guest,

    If that 635 is truly an AT&T phone then it will work with any AT&T network they own provided you have the micro-Sim from the carrier (as mentioned above). I have used both Straight-talk and Cricket Wireless in my 635 with no issues.

    A Straight-Talk sim card can be had at many retail locations "off the shelf" (like WalMart.) You get the SIM card and 30 days of Talk/Text/Data for something like $60. ($45/month thereafter)

    Personally I prefer Cricket Wireless (which is owned by AT&T anyway). It's about $10 cheaper per month with zero taxes but you only get 2.5GB of data versus 3.0GB. Something I can live with. Cricket uses the same towers and having used both networks now I don't notice any difference. Cricket retail locations are spotty but it's cheaper just to order your SIM and activate your account online.

    Yeah, watch out, because ST tends to push their TMobile SIM cards--you might have to hunt around a bit to get an AT&T one, and then search the forums here for the correct APN settings to get your data and mms working correctly. Personally, I would avoid ST due to their higher prices and notorious customer service issues. Cricket is a good option. H2O, Red Pocket, Air Voice, and PureTalk are some others. I'm currently using PureTalk with 500 minutes a month + 400mb of data for $24.95. No taxes, fees, hassle, and free SIM cards. You have to order the cards and set it up on the phone or online, but they have US-based customer service who are friendly and helpful.
