gang kelan po ba ung warranty ng tatto stick ?
It actually depends in your location. There are some location that you can have an HSPA or H+ connection and 4G connection (LTE) have a very limited area. You can check this for LTE sites https://www.globe.com.ph/help/all-about-lte-and-iphone-5-faqs
And I think, the same with my plan, you need to have LTE provisioned and activated. The 4g Tattoo stick means that it can acquire a 4g connection but it doesn't necessarily mean you will have 4g because 4g/LTE is only for postpaid subscribers.
