Now that the PLDT-Digitel merger has been finalized, Smart and Sun Cellular can now offer tandem plans for both network’s subscribers. They’ve now introduced the Smart Sun Dual 549 Plan.

The dual plan combines Smart’s very popular Unli Plan 349 and a custom/add-on Sun Plan 200 for unlimited SMS between networks — all at Php549 per month.
The package also includes a free dual-SIM phone, a Nokia C2-03. Not sure though if the plan is available on both Smart and Sun Cellular or if it’s just one-way (Smart-only).
This could just be the first of many tag-team plans now that Smart and Sun are one.

I have factory locked iphone for smart so I was not able to use sun in my iphone.Does it mean I can use my sun sim in the iphone as they are mergerd now. But, the network is not good now. I have not been able to receive interenational calls in my phone since the time they merged.
