prepaid smartphones and unlocked cell phones

by girlpower7 / October 30, 2010 5:25 AM PDT

Hello. I have a question about prepaid smart phones. I am wanting to upgrade my phone. I currently have a Nokia 6010, that was under contract with AT&T, but contract expired. Am now on a month-to-month contract with AT&T.

Could I use my Sims card from my Nokia phone,in a prepaid smartphone and continue to use the AT&T network? Also, I would like to know which unlocked phones could I use my Sims card in?

Thanks in advance for any helpful information.

Yes you can use your sim card to other unlock phone and there are a lot of smartphone out there i guess you just have to check one. Here you can visit intouchsmartcards so you can check which one you like.

Know what you're getting into

All modern cell phones have a code that tells the carrier what make and model it is. You should be able to use the old SIM in a new smartphone but if it's a phone for which AT&T normally requires a data plan, they will eventually add that charge onto your monthly bill as soon as they detect the change. I'm not sure how AT&T handles this type of situation when it comes to prepaid service, or if they even offer prepaid service for smartphones. Just know that using an old SIM won't allow you to fool them into letting you slide with regard to any mandatory smartphone data plan.

Regarding which phones to look for, stay away from phones designed for CDMA networks like Verizon and Sprint - they're not compatible. Also, AT&T's 3G data network operates on a different radio frequency band from T-mobile.

Be very cautious and make sure the phone you're interested in is indeed unlocked before you buy it. Just because it's being sold at full retail price doesn't guarantee that the phone is unlocked (the iPhone is a great example).

Thank you fondy for telling me this! I have done some research on unlocked phones and there is alot of information to know. I can guarantee you, no matter how much we consumers try to get around dealing with the mega-corporate phone companies, they will still find a way to stick to us price-wise! You can't win for losing.

Take care.

Using sim cards in unlocked cellphones

I have a prepaid plan with Tmobile and i have used my sim card in unlocked cellphones with no problem. You may want to google Tmobile and check out their prepaid plans. They have a gold member feature where when you buy $100 worth of refill cards,your unused minutes last you a whole year. I love this feature. Good luck.

Question to Musicman
by Chigal48 / November 5, 2010 10:23 PM PDT

I have a T-mobile prepaid plan and recently bought the Samsung T139....I hate this phone. No camera, no client email....a lot of features missing. Can I swap the Sim card from the Samsung into another phone by another provider, let's say Virgin? The reason is that I find the cost of buying a phone from the prepaids is cheaper (usually less than $29) than buying the phone outright.

Are prepaid phones unlocked? How would I get an unlocked phone and swap Sims?

Try these two sites, and Cell2Get. They have a great selction of affordable phones. I have just ordered a unlocked Nokia 3220 for $54 and i also bought a case for it for $0.74. Sometimes you have to spend a little more to get a good phone. Please let me know how things turn out. Good luck.

By default, prepaid phones in the US are locked. Unlocking is not very difficult.

You can also try CellPhone Shop. They are really cool too. I simply google "where to buy a unlocked phone". Take care.

Light bulbs you shouldn't buy

There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
