after banning safcom completely, I settled on Orange and Yu prepaid. grps is gprs, so i never had much expectations. The new bundle by Orange i.e kshs 2000/- for 2GigaByte is really cool. I had to delete all settings on my 2 pcs 3g routers to setup Orange. BTW, I hear safcom are now blocking port 25 but its unconfirmed.
