Write to ajuda@mondialchips.com from the e-mail you used in the purchase.
Include the order code, which starts with MC, your device model and the destination. With that we can usually solve it in the first reply.
Two minutes that solve most cases
Check that the phone is carrier unlocked and supports eSIM.
Check that data roaming is on for the Mondial Chips plan and that it is selected as the data line.
Toggle airplane mode once. A good share of slow connection cases ends there.
