Hi @JinxLorica ,
Yes, Davao has its LTE coverage. Please refer to this link: http://www.globe.com.ph/help/data-and-network
All you need to do is get a LTE capable device. Have an LTE enable simcard inserted on that then have it activated in your account. Go to LTE locations in Davao. Done you can avail the LTE you ever wanted.
Make sure to have UNLI DATA/ UNLISURFING combo with that. To maximize your LTE experience..
Hope this helps.
