Singaporean visiting from overseas: Best place to sell my phones (NOT Carousell)?

Hi!

Singaporean visiting home for the first time in a while and super happy to be here. I’ve got two phones on me (an iPhone 14 Pro Max and a Google Pixel 7 Pro). I don’t have their boxes with me, but I’d like to get the Google Pixel 9 Pro on a plan.

I’ve heard about Reebelo (and darn, the co-founder is quick to defend on Reddit, I know) and SellUp. Not really into dealing with Carouhell because of the stories and the lowballing.

Anyone with recent experience can let me know if these two are worth dealing with? I know Singtel is an option but I don’t really want to pay for a line I won’t use (I live overseas) for goodness knows how long.

Thank you!
