Wi-Fi vs 3G on the P3100

How do you differentiate a Wi-Fi model from a 3G one? I just flashed a Wi-Fi variant over my 3G model, and now the phone is missing.

buddy its simple there is a sim card slot on 3g model but not on wifi...
And on flashing you didn't get any phone option bcoz wifi model firmware do not have any module for calling(gsm utility) like phone.apk etc...

1- As i understand you have the 3g model and flashed a rom made for wifi model and didi not find any phone functions it is normal as this rom you flashed made specifically for wifi only model so do not expect it to display phone functions as it is not designed to use you gsm module in your tab it is for another model without gsm module so your gsm module will not find app inside this rom to use its abilities so will remain dormant and silent
2- Regarding your question flash only the roms that say clearly it is for p-3100 not those for p-3110 or p-3113 as those do not contain gsm module so will work in your device but no gsm functions or phone functions will work if you flash a rom that says clearly in the instructions in the thread you downloaded from that it is for p-3100 so you are good to go and gsm and phone functions will work no worries
3- I read a reverse condition of yours as if one with for example p-3113 ( without gsm module or phone functions) flashed a rom for p-3100 (with gsm and phone functions) the icons of phone and messaging and contacts will appear to him but if he presses these icons no actions happen as no gsm module found in his device

You need to go into the firmware of the phone or call a provider who can walk you through it. There is a way to change it after you update the mobile data. Your almost there its just one more step and then you reset your phone.

Then why 2g works and 3g no? Both use 850/1900mhz (B2 and B5 bands)
