Awful. So inept it feels like a scam. Don't use. They took my money 8 days ago for 4x USA SIM cards with data bundle and recorded delivery (3-5 working days). Latest delivery date for recorded delivery was supposed to be 3 days ago. Still no SIM cards have arrived. Courier tracking number provided is either fake or invalid as no records found. Online chat help is polite but essentially useless - "We will escalate this to the higher team and they will reply within 24 hours" is all they keep saying for the last 3 days. No answers about when/if the SIMS will arrive in time. Now I am stuck - do I continue to wait into the last day before we travel to see if they can fix it or do I buy a whole new set of SIM cards somehow elsewhere? Really disappointing. Do not use.
