How to Check Carrier Compatibility



All phones listed on Glyde are required to be paid off in full and not associated with the previous owner's contract or payment plan. This makes used phones on Glyde compatible and ready to activate on the carrier listed (Verizon, AT&T, T-Mobile, and Sprint) and on associated MVNO and prepaid carriers such as Ting, Straight Talk, and Republic Wireless (for example, used T-Mobile phones can be activated on Ting). Unlocked models are also a good option for "Bring Your Own Device" carrier plans, but please see details below to make sure an unlocked phone will work for you. If you're buying a phone for an MVNO carrier, just check the guides below and double-check with your carrier to ensure you get the right model.

Unlocked

Unlocked phones are compatible with GSM carriers like AT&T and T-Mobile as well as with services that run on GSM SIM cards. MVNOs such as H20, Straight Talk and others offer this type of service, as well as select prepaid carriers. Unlocked cell phones may not work fully with CDMA carriers like Sprint, Verizon, Boost or Virgin or other providers that use CDMA technology. Some providers, such as Ting and Red Pocket, offer both CDMA and GSM plans, and an unlocked model may only work on the GSM plan.

MVNOs

MVNOs or Mobile Virtual Network Operators are smaller carriers such as Cricket Wireless, Credo Mobile, Ting, and Red Pocket. Used phones on Glyde will work on MVNOs, but be sure to check with your MVNO to confirm which models are compatible on their network. We also recommend checking out Whistle Out to see a list of compatible models and BestMVNO.com to see a list of Verizon MVNOs, AT&T MVNOs, T-Mobile MVNOs, and Sprint MVNOs.

Verizon

Verizon phones run on the CDMA network. Used Verizon phones sold on Glyde can be used on Verizon. Some LTE devices such as newer iPhones may also support GSM network voice and data services, but data may be limited to 2G or 3G networks. Some used Verizon devices can be activated on MVNO carriers such as Red Pocket, Net10, and Straight Talk.

AT&T

AT&T phones run on the GSM network, and most require a new SIM card from your chosen MVNO carrier. Used AT&T devices on Glyde can be activated on AT&T or brought over to MVNOs such as Cricket and Consumer Cellular. Check with your MVNO or prepaid carrier to ensure your device will work and to check SIM requirements.

T-Mobile

Like AT&T, T-Mobile phones run on the GSM network and require a SIM card. T-Mobile phones listed for sale on Glyde will work with T-Mobile. Associated MVNOs include Ting, MetroPCS, and PTel.

Sprint

Sprint phones run on the CDMA network, but are not compatible with Verizon. Each used Sprint phone sold on Glyde has its IMEI or ESN checked to ensure it is ready for activation on Sprint or associated MVNOs. Common Sprint MVNOs include Ting, Republic Wireless, and FreedomPop.

When you're ready to buy, visit Glyde to find a great deal. If you have a phone that you've previously used on an MVNO, it cannot be sold on Glyde due to software modifications. However, phones used on Verizon, AT&T, T-Mobile, and Sprint can be sold here.
