so i got my dream flip phone and it's arriving in a few days (YAAAAYYY!!) it's a sony ericsson z610i in blue and it came in its box with the charger and dvd and manual and everything. but right now my only concern is finding a compatible sim card for it.
from what i know the z610i runs on 2g and 3g networks. i live in portugal so the three big carriers are meo, vodafone, and nos. preferably, i'd love to have a vodafone or meo sim card, since i've used vodafone for all my phones so far and my internet provider is from meo. but if there are any other cards that are compatible with my phone i'm more than happy to purchase that too.
i get so confused when i'm looking for sim cards online and it only says "compatible with 5g networks." okay but is it backwards compatible with other networks?? i need to know!
thanks in advance <3 (if this is the wrong topic of discussion i can take the post down)
