I’ve poked around on this topic a bit, and here’s what I found. Typically, carrier-branded devices do have slower firmware and OS updates because the new versions get modified for the carrier’s features and apps before release. Those pre-installed apps can sometimes hog resources or storage, impacting performance and battery life. As for network features, some users report better optimization on Globe-branded devices, but others say they work just as well on unlocked models, so it might come down to specific handset models.
Regarding resale value, carrier-branded phones often fetch lower prices due to perceived limitations. But, warranty and support from Globe might be easier to deal with for network or carrier-specific issues. If that service is important to you, it could be a factor. It seems like it boils down to whether you value convenience and possibly better network features over the purity and potential higher resale of unlocked devices.
