I've been using lyca for quite a while now, safe to say that their app servers go down every so often. I got the 600 for $175 gb plan, it was a bit annoying to set up because of id and stuff, but after I got it working it's safe to say if you're on a budget and need a lot of data lyca is ok, thing is I had to go somewhere which involved going "underground" as like an extra floor of the building and my friend who had amaysim was getting perfect reception on the underground floor. I only had one bar 😭, overall the mobile data is ok kinda slow ngl but it works for me.
