I can modify for free any GSM 3G capable tablet you may purchase that you would rather not have to give money to telecoms people to use.

I can do it remotely too. Basically it involves not buying or installing a sim card. I'll provide more details about how to do this once you get your tablet

I am the other way around. I would prefer every computing device I had to have 3G capability - just in case. I could then take the sim out of my phone and put it in my laptop / tablet if needed. Even though these occasions don't arise frequently, in my life it would make a big difference in that moment when they did. Options are always better for me.
