i think these telcos will shift their services that will rely heavily on DATA.. globe now has this GOMO sim which you pay say 300 pesos for 30gb data which you can convert the data into "calls or text" load..
also, for you to be able to transfer networks, you need to register the number to your name.. hence pag nawala, just call the operator and they can immediately deactivate or block the sim.
their plans now are very attractive.. sa globe, may 599 plan that have 5 or 10gb of data with unli calls and text to all network and landline..
for me mas cheaper na ito at hassle free compared to prepaid na almost 500 din ang magagastos mo sa load.. tapos nakakalito pa humanap ng promo..
