BEST GSM PDA CELL PHONE taking a .. SIM card?
What is the best GSM mobile phone (PDA), in his opinion ,…. MUST HAVE A MAP SIM .. I want something like the Palm Treo 680 … THX
Even the iPhone has a SIM card [of course locked to a single provider, but you can change the SIM card if belongs to the same provider] and has all the functions of a PDA equipped and many additional features. A little expensive but worth it for sure … Impressive facility for use in email applications, etc..
