Enjoying my new PLDT Smart Enterprise SIM only Plan 1500 . No lock-in period. They asked for copies of DTI registration and business permit and 2 months advance payment. Inclusions: Unlicalls to all networks (except special numbers eg toll free like 1-800, fast food delivery #s), unlitext to all networks And of course UNLIsurf! (it was a promo until June 30 only). Now its 48GB/month the last time I checked.
