Yes, definitely! International roaming is expensive so we recommend that you buy a local SIM card (Beeline, Ucell, etc.) at airports or official stores with a calling and data plan for $2-10. Registration of an Uzbek SIM card requires your passport. Be sure your mobile phone is unlocked to use local SIM cards. You will also need to register your phones IMEI number with the Uzbek authorities if you stay longer than 30 days. You can do this online with a small fee at: https://uzimei.uz/en

Another good option is to buy an eSIM with a data plan in advance of arriving in Uzbekistan. This might be more expensive than a local SIM card for the data plans, but you would still have access to your home phone number.
