I've just gone through the process of adding data @ T-Mobile & it really couldn't be simpler.<br><br>The one guideline you need to be aware of is that you CAN NOT get data GPRS or EDGE on a pay as you go plan (T-Mobile to go). It has to be on a post paid monthly account. To my knowledge and research, neither AT&T or T-Mobile will permit a data package on a pay as you go basis.
<br><br>Assuming then that you're on a montly plan. You just need to request that they add the unlimited T-Mobile Web to your account. This is $5.99/month. On the surface, it just gets you the WAP service .. but that's all you need.
<br><br>Last week I decided I needed a more production solution than the v1 Moko will be and bought a Motorola Roker E6 direct from Hong Kong. Sometime soon I'll post some thoughts about the E6 that I think are pertinent to UI issues w/ Moko. I got it tweaked to Quad Band and Edge and activated it on T-Mobile, with little or no difficulty. You will find TONS of information on the data settings at both
HowardForums.com and also at MotorolaFans.Com.<br><br>I encourage you to not seek out the "total internet" or "Smartphone packages" .. you don't need to pay the extra $20/ month.<br><br>Good luck.<br>
