Are there any carrier restrictions when purchasing a device from Ecobuyphone?
There are no strings attached when you purchase a device from Ecobuyphone. No contract extensions, no hidden fees, and no requirement to stay with or switch to a new carrier - just straightforward pricing based on the value of the device. We carry devices for major carriers as well as unlocked phones, which can be used with multiple major carriers and smaller carriers/MVNOs.
Is your phone compatible with my carrier?
We offer a large variety of both carrier-compatible and unlocked devices. Please note that it’s important to choose your specific carrier when purchasing a Ecobuyphone certified preowned device, as we can only guarantee it to work with the selected carrier. For example, we can only guarantee that a Ecobuyphone certified AT&T device can be activated on AT&T; we cannot guarantee that it can be activated on any other carrier, and we cannot guarantee that it can be unlocked.
We can also only guarantee that your Ecobuyphone certified preowned device will work domestically within the United States. We cannot guarantee that it will work internationally.
Our unlocked devices are generally GSM & CDMA compatible and will work on all major US carriers (Verizon, AT&T, Sprint, T-Mobile) and most MVNOs. Unlocked devices may not work in non-LTE coverage areas. For international travelers: Unlocked phones will work on most international GSM networks, but may have limited access, depending on carrier.
What is an eSIM or SIM card?
SIM is short for Subscriber Identity Module, a unique identifier inside every cellular device that enables wireless service providers to know the user's assigned phone number. The SIM card stores your personal data and may be removable, depending on the device. The “e” in eSIM means embedded. An eSIM card is hardwired into the phone itself. Because of its advantages, eSIM cards are replacing nano cards in newer cell phone models. - fcc.gov

Will a 4G SIM card work in a 5G SIM Device?
Most carrier networks recommend receiving a new SIM card from your carrier network for your device, to receive their full network experience.
Some 4G SIM cards may work with 5G devices, but we recommend following best practices, and replacing your current SIM card with a new one when activating your new device.
If you are switching carriers, you will need a new SIM card.
