The first step is to make sure that your specific device is compatible with the 4G/LTE radio signals that your carrier uses. You can review what the device capabilities are here:
You likely will have to ask your carrier if their network operates within what your specific device supports. If they are not compatible, then you are done...if your carrier operates on radio frequencies that your device does not support, there is nothing you can do to overcome that.

my carrier uses LTE 800/1800/2600 Mhz frequencies. My BB Q10 SQN100-3 supports LTE 800/900/1800/2600 Mhz frequencies. Problem is that with T-Mobile Slovakia SIM card is enabled only 2G, 3G and 2G & 3G in the Network Mode menu. 4G variants (4G&3G, 4G&3G&2G) are not listed in the Network Mode menu. I often use T-Mobile Austria SIM card in Austria and with my BB Q10 has all 4G variants in the Network Mode enabled. If I change my T-Mobila Austria SIM card to T-Mobile Slovakia SIM card, my mobile device will connect for very short time (2-3 seconds) to T-Mobile Slovakia 4GLTE network. After 3 seconds 4GLTE icon is changed to "No Signal" and device is connected only in to T-Mobile SK 3G/H+ network. I think my device is capable to use 4G frequencies of my carrier. It seems carrier settings are not upgraded for use in 4G network. I called customer technical support line today and operator told me: "We have already approved and released carrier settings firmware for BlackBerry 4G capable devices uses T-Mobile Slovakia SIM cards. T-Mobile Slovakia is still waiting BlackBerry will released carrier settings via OTA update for our (T-Mobile Slovakia) customers". If it is correct information, probably BlackBerry can help. Do you have information when could be carrier settings upgrade available over the air?

Thanks for you answer. I am not trying to roam on the Slovakia network. I use T-Mobile Slovakia SIM card in the Slovakia and I use T-Mobile Austria SIM card in the Austria. I am only trying to investigate, why my BB Q10 is able to use 4G network with T-Mobile Austria SIM on the Austria network (not roam) and why the same BB Q10 device with T-Mobile Slovakia SIM on the Slovakia network (not roam) is not able to use 4G network. With the same T-Mobile Slovakia SIM card inserted in the Samsung Galaxy S4 mini, S4 mini is able to use 4G network (BB Q10 is not able to use 4G on the Slovakia with T-Mobile Slovakia SIM card). LTE is activated on mentioned T-Mobile Slovakia SIM card. Customer technical care told me, that T-Mobile had approved carrier settings upgrade and they were waiting for BlackBerry would release FW OTA. You wrote all things were controlled by carriers for realease to their customers. I think it is complicated situation. T-Mobile Slovakia is waiting for BlackBerry and BlackBerry leave it to carriers, T-Mobile SK too Probably I have to wait for the time carrier upgrade will be realease OTA.
