Changing Phones


Oct 15, 2008, 6:34 PM
I currently have a Motorola i335 which is starting to act up. I would like to switch it out with another phone. I have an old Motorola i870 without a SIM card. When I install the SIM from the i335 into the i870, it does not work. I assume there is a incompatibility with the SIM card and the two different phones (however it seems that the research I've done contradicts that). The SIM card I currently have is the 128K (black) one.

So two questions:

- Is there a way to copy the i335 SIM card to a new SIM card compatible with the i870, and what parts would be required to do so? In other words, how do I "make" my current SIM card (or another) compatible?

- If the first option is impossible / impracticable, which phones are compati...

If the sim works in the 335 and not in the 870, there is probably something wrong with the i870. Try a different sim in the i870 and see what happens. My bet is it won't work with any sim.

i have seen that happen where the black sim will not work. the new ones (falcon 128k i think) are yellow. there is a way to get you numbers (if they are on the sim card) off of one and put on another, all you have to do is go into a sprint store and ask them to transfer them with their cellbrite machine.

Ok, I know this is old but...All you have to do is grab a different phone, call custmer care and they can activate the phone & sim card together. They'll walk you through a master reset and voila!
