Yes—you have three strong long-term eSIM options: Google Fi, Visible, and T-Mobile Prepaid, with your exact unlocked Flip4 compatibility deciding which ones will activate.
“I'm an international student staying in the US long-term. Mint Mobile no longer seems to support eSIM for my Samsung Galaxy Z Flip 4. What are some good eSIM alternatives for long-term use in the US?”
Resumen
Samsung itself lists the Galaxy Z Flip4 as eSIM-capable, so Mint’s result does not mean your phone has no eSIM. The manageable part is confirming your exact regional model, unlock status, and carrier compatibility before paying.
You have three practical monthly routes, with the best choice depending on your exact handset compatibility, budget, and data needs.
Google Fi’s official compatibility help names the Samsung Galaxy Z Flip4 and says compatible Samsung phones can use eSIM; your phone must be unlocked. Unlimited Essentials is $35 per month for one line, includes unlimited US calls and texts, and provides 30 GB before data slows to 256 kbps; taxes and government fees are extra. Fi has no annual contract or activation/cancellation fee (Google Fi BYOD Help; Google Fi Plans).
If Visible’s compatibility flow accepts your exact phone and it is unlocked, the base plan is $25 per month with taxes and fees included. It includes unlimited talk, text, and data on Verizon’s 5G/4G LTE networks plus unlimited hotspot at speeds up to 5 Mbps; activation is through the Visible app over Wi-Fi (Visible Plans; Visible eSIM).
If T-Mobile’s checker recognizes your and reports that the device supports eSIM, its web activation works with an unlocked phone. The 15 GB plan is $40 per month with AutoPay after a $45 first month, while unlimited is $45 per month with AutoPay after a $50 first month; taxes and fees are additional (T-Mobile Prepaid Plans; T-Mobile Prepaid eSIM Activation; T-Mobile IMEI Checker).
The words “Galaxy Z Flip4” alone do not guarantee activation: Samsung warns that country of origin and carrier support can change eSIM availability.

These steps confirm the phone first, prevent an unusable purchase, and preserve your current number during the switch.
Before buying a plan
Confirm eSIM and unlock status
Open Settings > Connections > SIM manager and confirm that Add eSIM appears. Collect the 15-digit and 32-digit ; T-Mobile places the EID under Settings > About Phone > Status. The phone must be unlocked for Google Fi and T-Mobile, and Visible also tells switchers to make sure it is unlocked (Samsung Galaxy eSIM Support; T-Mobile IMEI Checker; Google Fi BYOD Help; Visible eSIM).
Requisitos
Before payment
Run all three compatibility paths
Use Google Fi’s official checker at https://fi.google.com/compatibility, Visible’s checker at https://www.visible.com/shop/compatibility?intcmp=LP:ESIM:Compatibility, and T-Mobile Prepaid’s checker at https://prepaid.t-mobile.com/bring-your-own-phone/imei-check. Continue with Visible only if its flow accepts the phone; continue with T-Mobile only if its result says the device supports eSIM. If both reject it, Google Fi remains the strongest candidate because its official help names the Galaxy Z Flip4, subject to the unlock and regional-variant caveat.

Do not terminate your service with your existing company before initiating new service with another company. Contact the new company to start the process of porting your number. Provide the new company with your 10-digit phone number and any additional information required. FCC rules require simple ports, which generally do not involve more than one line or more complex adjustments to telephone switching equipment, to be processed in one business day. You may be able to use your phone within a few hours for changes among wireless service providers.
