====== Carrier compatibility ====== This page does not list band compatibility per carrier as carriers can differ on supported bands by region. See [[radio_bands|]] for information on supported frequencies by device. Additionally, if you are looking into a particular device's compatibility on a network, see if the phone has a dedicated page on the subject before reading this page as compatibility may differ by device. This page is for general information on various carriers and their [[wp>MVNO]]'s in regards to their compatibility with Garaho phones. Some carriers employee whitelists for using VoLTE (4G phone calls), which can cause a non whitelisted phones to not be able to make calls. This and other carrier specific information may be found on this page. ===== VoLTE whitelisting explained ===== Some carriers have strict phone specific whitelisting for the registration of [[wp>IP_Multimedia_Subsystem|IMS]]. Without IMS VoLTE will not work. VoLTE is how calls function over a 4G network and so with many countries undergoing a 3G shutdown some carriers no longer support calls at all on some devices. ==== Canada ==== Currently in Canada 3G is being phased out, with some carriers already having phased it out of their networks, and the rest are in the process of doing so[(https://crtc.gc.ca/eng/phone/mobile/3g.htm)]. === Telus (Koodo, Public Mobile) === Telus and their MVNO's do not seem to have a whitelist in place, and IMS has been found to be registered on the A202KC[(https://www.reddit.com/r/dumbphones/comments/1gxfrh9/kyocera_digno_a202kc_working_canada_koodo/)]. === Rogers (Fido, Chatr) === Rogers and Fido are generally known to have a whitelist in place for IMS registration[(https://www.reddit.com/r/FidoMobile/comments/1lv86j9/lte_vs_volte_and_whitelisting/)]. The A20XKC[(https://discord.com/channels/1448460944626684047/1504227896011522080)] and KY-4XC[(https://discord.com/channels/1448460944626684047/1448460945323196569/1517277429075546212)] do not seem to be on the VoLTE whitelist[(https://discord.com/channels/1448460944626684047/1483296895504875591)]. However the 90XKC seems to be able to register for IMS[(https://discord.com/channels/1448460944626684047/1504227896011522080/1506116839795720394)]. This may be due to SoC differences. === Bell (Virgin Mobile Canada, Lucky Mobile, Loblaws, PC Telecom) === Bell does not seem to have an IMS registration whitelist[(https://www.reddit.com/r/bell/comments/1lyzxqe/comment/n2z5h4y/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)]. === Freedom Mobile === Does not seem to have a whitelist, needs further research. ---- ==== United States ==== === T-Mobile US (Mint Mobile, Ultra Mobile, Tello) === Notably, users of the [[phones:kyocera_digno_keitai_4:|KY-42C]] have been able to receive updates through T-Mobile and it's subsidiaries[(https://www.reddit.com/r/garaho/comments/1rk17nl/kyocera_ky42c_new_software_update/)]. ---- ===== Italy ===== ==== Vodafone Italy ==== ---- ===== U.K ===== ---- ===== Australia ===== Needs expanding, see: https://www.reddit.com/r/dumbphones/comments/1kalghp/japanese_flip_phoneskeitais_australia/
