Why is my LG K10 not supporting 4G?

[Android Central Question]

I have an unlocked AT&T LG K10 phone using a simyo sim card in Spain and it is not supporting 4G. Please tell me there is something I can do to fix this.

Thanks for your help.

Welcome to Android Central! Your phone doesn't support Simyo's LTE bands. Simyo uses the Orange network in Spain, which uses bands 3 and 7 for LTE: https://www.frequencycheck.com/carriers/orange-spain. The K10 doesn't support them: https://www.lg.com/us/cell-phones/lg-K425-k10. Sorry!
