I'm in PI now. I use Tmobile, but it can be pretty slow in some areas (was in Bataraza, Palawan a week ago). I have a dual sim Pixel 7, so I run a prepaid globe sim. There's no end to the plans you can get here (and for very little). Some of the choices include unlimited data, but only for a handful of services that you have to pick from a list, other's just data that everything consumes and as other have said, some are little to no data and just texts or calls.
I have been using a 129PHP (roughly $2.50) promo plan with 8GB data, unlimited all network calls and text for 10 days. But there's at least 70 plans in the Globe app to choose from and every day I get 1 to 2 texts from globe with other promo plans.
(Also have a SMART Sim just in case I get stuck somewhere with poor Globe service.....Less than $1 for a prepaid sim)
