PDA phone or a dual sim phone?  

If you are in business you should not replace the pda, the dual sim phone might not be capable of handing 2 sims at the same time and hanging a lot. That will cause you a lot of trouble.
Make sure you have seen reviews of the new phone you are planning to buy.
The other option is to take another mini cell that will be for your rough use, this will also help in situations of backup and emergency .

I guess PDA Phone is better than dual sim phone as Dual sim might cause a lot of troubles most especially from those not so popular brands.. i have tried using PDA phone and I liked it.. at first, i fnd it complicated to use but after a week or so, i've gotten used to it.. you can do a lot to PDA phones such as editing documents, reading ms office files, etc..

I would go for PDA phones... There's so much useful things to do with PDA phones than Dual sim phone. I already did tried using a dual sim phone and a PDA phone and PDA is much better. Much better if its PDA phone with Dual sim. :D

PDA is good option for people in business field than dual sim and PDA phones can do lots of stuffs which might be available in dual sim phones and even if you are going to buy a dual sim phone just check its review online before buying it as most dual sim phone wont be good..

Hey,

Yea PDA's are quite good, but I have to admit, dual sim card phone are actually quite handy. I honestly like them, I just wish all mobile phone makers would start making their phones to have dual-sim card capability. Make sure you have a good day, Happy Lotting!!
