An unlocked Android phone can be used with any GSM carrier, providing you are in a location with cell service. A locked Android phone is tied to a specific carrier. This means you can only use it on the network of that carrier. If you attempt to use a locked phone with another carrier's SIM card, it will not work. You can sometimes unlock a locked phone by contacting your carrier and asking for an unlock code. The unlock code is unique to your phone. The cost to unlock can range from free to several tens of dollars depending on the carrier, your account status, and your phone contract. Whether a phone is unlocked or not doesn't change the phone's storage capacity (128GB in this case). That relates to the internal memory, which holds apps, photos, videos and other data and is independent from the phone's carrier.

From a purely technical standpoint, the difference lies in the phone's cellular radio firmware. A locked phone has restrictions programmed into its firmware that prevent it from connecting to networks other than the carrier it was originally sold with. An unlocked phone lacks these restrictions. The storage capacity (128GB in this instance) is an entirely separate hardware specification, unrelated to network compatibility.
