Local sim card at 7-Eleven

I'll be travelling throughout the Philippines close to 30 days.

My phone doesn't support e-sim.

Can I buy a sim card at 7-Eleven (or any other convenience store) to avoid the pricy tourist sim card at the airport?

If yes, is it easy to top it up with data along the way? And do I need my passport to register the sim card?

Edit, prices according to official stores, users, youtube lol:
