If you dont wish to have problem receiving and sending emails
using blackberry when overseas.
My kind advise to you is never subscribe to M1 services.
I was in Nigeria for a month project and needed to received
urgent and important emails. However i got problem
sending/receiving emails using blackberry
I called M1 using my phone and they advised me to do some
settings which i did. However still unable to ... (i
spent 20 minutes talking on phone with M1). after much
attempts... they told me that M1 do not have any partnership with
Nigera!
WTF! If i ever knew that M1 doesnt cover most of the
countries, i wouldnt have sign up in the first place, and causing
me to pay a hefty sum for their useless technical support!
