1. I placed an order the day before, but the next day when I arrived at the pickup location at the airport, the type of SIM I ordered was not available. Time was rushed because the booth opened at 7:30 but I had to board at 9:00, but it took a long time to find a solution which was to replace the SIM card and give it to me.
2. After flying to a foreign country, the sim card inserted at the airport did not work. But perhaps the most important SIM card is when you first arrive in another country. It took 2 hours of struggling with the police, the phone ran out of battery, and the SIM finally worked.
Although the support is good, the product is poor. I will not order again.
