I've now bought and used 30-40 eSIMs in various countries and some are better than others. But by far, Airhub is the WORST. Did not work at all in some countries that were advertised (Canada/Monaco) and customer support was a bang-your-head against-a-wall situation.

NEVER AGAIN.

Bought the "Europe 30 Day 1GB" E-sim connecting to the O² network in the UK. Works great, and getting the exact same connection speeds (25-35mbps) as my friend's phone which is using an O² SIM.

SIM simply did not work in Singapore and support was non existent!!
tried to get me to use their portal which wanted me to accept cookies without information on them, a real no no.

SIM supplied for UK was not as advertised connected to EE not O2.

Will not be using them again!

The service was okay on 5G, but the moment it switched to 3G or LTE it was horrible - slow, to non-existent, frustrating and unreliable. I would try another provider next time.

The eSIM works well as expected in the 3 countries I visited recently: UK, Thailand, Taiwan. They send reminders when data is almost used up.

Bought the Global YO Global 100 10GB/30day for $10. It would not activate in UK. No service, no signal, even trying manually connecting to all 4 avail networks. Have tried to contact support. Have never had this problem with Airalo, Nomad or Airhub.
