How to replace 1gb to 2gb memory card in nokia 7210 with out loss of informations

That's a good looking phone - haven't seen that model in the Uk yet.
I have looked at the spec on the link below // http://www.fonearena.com/nokia-7210-supernova_706.html
The phone only has 30MB of internal memory yet stores music , photo's & video. This 30MG will fill up very quickly with just 30 music tracks.
There is a MicroSD memory slot - I would suggest a 1GB min - 2GB better if you take video.

im really sorry! the only way to fix it is to format the sim card ( on a different phone, the 7210 doesnt have this option) the problem is when you format it all the info on the card is erased. i had this happen to one of my old phones and it was just easier to get a new sd card. i picked up a 1gb from walmart for $9.88 i hope this helps!!!

Will it boot with only ONE of the 2GB memory-sticks installed?
Will it boot with ONE of the 2GB memory-sticks AND one of the 1GB memory-sticks?

Look closely at the 1GB memory-sticks.
Does the label show 'DDR266' or 'DDR333' or 'DDR400' or 'PC2100' or 'PC2700' or 'PC3200' ?
Do the 2GB memory-sticks have _identical_ information?
It's definitely _not_ acceptable to have "slower" RAM (smaller numbers) in the new RAM,
but it _might_ be acceptable to have "faster" RAM (larger numbers).

try to read the data using some other nokia 7210

or

try using memory card reader available in market, using them u can copy the data to pc

You can change your memory to 2GB if the present one is full. connect the mobile using the cable to the PC. the mobile will shut off and you can go through the files within the memory. save off the files to the memory card and relieve your memory. Also you can transfer off files to your PC and keep the required ones. I hope this will help you out. Good day

is it formatted? if not try to do so

Thanks to Microsoft Knowledge Base for help with my answer:

First, find out what the maximum amount of memory is. This is generally listed by most of the manufacturers. This will let you know what upgrade potential the system has. Next, determine how the memory configuration is when you buy the system. For example, a laptop that has 2GB of memory can be configured as either a single 2GB module or two 1GB modules. The single memory module allows for better upgrade potential because by adding another module you are gaining more memory without sacrificing any current memory. Upgrading the two module situation with a 2GB upgrade would result in the loss of one 1GB module and a memory total of 3GB.
