I bought a zitron set yesterday. Transferred my sim card from my trusty old E61 into the E71 but I can't seem to surf using the wifi or 3G. I get an error message which says "Packet data not allowed" or "No gateway". I hope someone here can help or else I will have to make another trip back to the shop.

Thanks in advance!

Thanks mikelanding and viravira. I solved the 3G problem by deactivating the APN control but I am still having a problem using the wifi. Not sure if my home router is the problem. Will have to go out and try a public wifi to see.
