4G need to be enabled by your carrier provider and by phone settings.

Hi Delberth,

Welcome to the community,

You may also want to check if your device is set to pick up LTE.

Menu > Settings > More > Mobile Networks > Preferred network type > Choose LTE or 4G

[Delberth]

I already do that and still does not work

@Delberth

settings > about phone > which phone variant do you have ?

How old is the SIM card?

It seems that in Costa Rica LTE bands are 1800 and 2600

LTE band

1(2100), 2(1900), 3(1800), 5(850), 7(2600), 8(900), 20(800) - E2303

2(1900), 4(1700/2100), 5(850), 7(2600), 12(700), 13(700), 17(700), 28(700) - E2306

1(2100), 3(1800), 5(850), 7(2600), 8(900), 28(700), 40(2300) - E2353

Also you will have to check with your carrier network the 4G network coverage.
