Any help would be appreciated.Thanks

Huawei Y6p has encountered the same problem before on this device. You can check there is a SIM card.

After the SIM is inserted, the country code of the SIM card will be read. Rules for obtaining the country code: country code of the place of shipment> country code of the sim card> country set by the mobile phone.
