Fairphone 4
Hi I bought a Fairphone 4 which seems to be mostly compatible with my phone in the USA. I can get 5G mobile speeds on this phone. (Yes!) But then when I try to use the built-in Google Messages app using the default settings from my T-Mobile SIM it gives me a "Can't send messages with T-Mobile, Error 50" notification. Everytime I try or resend it seems to give me that message. I have tried changing APN's and copying it from my old phone that worked to the new one and seems to do the same thing. But when I pop it into the old phone it says it works. When I switch from the Fairphone 4 to my old phone it says from 2903 "We see your phone does not have correct settings to access the internet or send MMS. Settings will be sent to your handset." And I click the messages and it downloads the settings again to my old phone and still works. But I can't get my new phone to recognize. Fairphone is a European phone but the bandwith is essentially the same. The fact that it can access internet and pull 5G internet means it can go online. I would think this would enable it to also send SMS/ MMS. In fact when I try to send text SMS it gives me that Error 50 message. But when I do a picture MMS. It looks like it goes through, but never appears on the receiving phone. And also the antenna symbol has an "X" on the bottom. That's the triangle wedge on the top of your phone screen that shows how many bars and how strong your connection is. But I don't think that's the problem because when I turn on data it shows 5G Basic. So on my older phone it shows 5 APN's: T-Mobile fast.t-mobile.com T-Mobile LTE fast.t-mobile.com LTE Attach Profile T-Mobile IMS ims T-Mobile Emergency sos But the Fairphone 4 when I load the SIM in there shows only the T-Mobile USA APN and no others. I have tried manually adding and also T-Mobile settings shown here: https://www.t-mobile.com/support/devices/not-sold-by-t-mobile/byod-t-mobile-data-and-apn-settings I checked the settings and the Authentication type for T-Mobile says PAP while my Fairphone 4 uses the None listing. There are also additonal settings in the Fairphone 4 APN type: default,supl,hipri,xcap,mms APN protocol: IPv6 APN roaming protocol: IPv4 Bearer: HSPA,VDO_B,eHRPD,LTE,HSPAP,GPRS,EDGE,UMTS,IS95A,IS95B,1xRTT,EVDO_0,EVDO_A,HSDPA,HSUPA MVNO type: GID MVNOvalue:544D And on the data screen I have MMS messages: Send and receive when mobile data is off Preferred network type: 5G/4G/3G/2G and Automatically select network defaults to T-MobileSolved4.1KViews3likes10Comentarios
