  1. [R2] Rebtel 5/5 · US Siempre uso esta Aplicación y funciona perfecto: Funciona muy bien
  2. [R3] Rebtel 3/5 · US Buena pero tiene sus problemas: La verdad la aplicación es muy buena, y comparada con otras, es económica, qué problema veo, que hay días que se traba y no salen llamadas, el saldo no se refleja algunas veces bien sino que sale 0$ teniendo saldo, y hay países que de plano no salen llamadas como es El Salvador. Trabajo con la aplicación y algunas veces me ha tocado recurrir a otras aplicaciones
  3. [R5] Rebtel 5/5 · US Cálidad: Exelente servicio
  4. [R6] Rebtel 3/5 · US The sound quality was fine until it simply cut off. I: Although I am happy with the rates, every call I have made to date has abruptly cut off. This waste immense time and cost extra money.
  5. [R1] Rebtel 1/5 · US Insanely low rates: They bring you in with discount then their price go up insanely high.
  6. [R7] Rebtel 1/5 · US Charging for just ringing: This app charges a min per ringtone!
  7. [R19] Rebtel 1/5 · US Estafadores: Una linea q solo te roba el dinero envias un paquete a otro pais y nunca llega pense q la targeta era el problema y le paso a mi amigo igual perdi dinero en está ap
  8. [R22] Rebtel 1/5 · US Stealing: I use it often this app but the problem is sometimes it steal money
  9. [R25] Rebtel 1/5 · US Ladrones: Eh realizado un pago en la app y nunca llegó una recarga que eh echo !
  10. [R26] Rebtel 5/5 · US Charged after cancellation: Getting charged after subscription has been cancelled and payment information has been removed! No help available besides their useless bot…
  11. [R4] Rebtel 1/5 · US No resolution from customer service!: This used to be my favorite app to use for years! Especially the customer service even if it is relatively pricey. Now they stop actually trying to resolve the problem and just beat around the bush.
  12. [R10] Rebtel 1/5 · US Bad service now: I have been a RebTel customer for 10 years. Their Service used to be good. Now calls drop after 2 mins of being on the phone with people in Dubai or Kerala. The support process is very difficult. There's no simple way to get in touch with a human. They create and innundate with support tickets but nothing every happens. They close the support ticket saying I didnt respond. but
  13. [R18] Rebtel 3/5 · GB OTP failure: Unfortunately often the one time password feature often doesn’t arrive in your phone. Once it’s set up it’s ok, but the support takes time to get back to you and if you need to revalidate, you could be waiting a little while. But when it’s installed it works very well.
  14. [R15] Rebtel 3/5 · US Good app when it works: I like the monthly schedule. It is very affordable and call quality is generally good. However, it’s frustrating when I try to make a call and the app can’t connect to Reptel server, making it impossible to make a call or seek support via the app. This happens even though the device is connected to fast WiFi internet connection.
  15. [R21] Rebtel 3/5 · GB Not as promised: Downloaded the app and at start registering verification code never received even after trying 5 times.
  16. [R9] Rebtel 3/5 · US Connectivity: Very nice. No air drop. Clear voice.
