call forwarding just does not work
i have had a perennial issue with call forwarding for the last 2 years and it has become a real pain, so i'm looking to finally solve it this time, if one of the at&t support guys can help. each time i go abroad, i want to just forward my wireless number to another line (in the u.s.) and turn off my phone, but up to this point it has never worked. i have a samsung galaxy s8+, and have tried both of the following methods: **21*[number]#go to settings-supplementary services-call forwarding-always forward, turn on and add the numberboth methods have exactly the same effect, they say that the phone has been forwarded unconditionally (mmi is successful), and i even get an icon in my notification panel stating that call forwarding is on unconditionally. now my phone never rings. so, here's the problem....if i call my number from another phone it just goes straight to voicemail. i have tried all of the following with no success:leave the phone switched on and on the network: it doesn't matter how long i leave it on for, the call forwarding never goes anywhere, all calls just go directly to voicemail, and not to the number i forwarded toturn the phone off completely....same as above, it doesn't helpforward to several different numbers including another at&t wireless number and even a landline...it doesn't matter where i try to forward to, as soon as i turn on call forwarding all incoming calls just go directly to voicemail and not to the number i forwarded to.am i missing something here? as far as i can tell, call forwarding just plain doesn't work on at&t, any attempt to turn on call forwarding will say it is on and then just forward all calls directly to voicemail. pleease help, i'm getting desperate. thanks
after some playing around i managed to fix this problem. the issue appears to be a forwarding priority problem. there are 4 types of call forwarding which are supported by at&t and most devices, they are: unconditional call forwardingforward on busyforward on unansweredforward on unreachable according to some earlier posts in other threads on this forum it is currently impossible to set anything other than unconditional yourself (even for unconditional i'm not sure, although it appears to work), apparently at&t disabled this some time ago citing security concerns. so, in order to set the others, you need to call 611 and ask at&t to do it for you. so, to the issue. in my case (and i believe in most cases), the default call forwarding number for all of the various types of call forwarding is the voicemail number for at&t (starts with 415 area code). what appears to happen if you try to set unconditional call forwarding yourself is that it appears to have worked, but when someone makes a call to the number, at&t defines the phone to be unreachable, so, instead of forwarding to the unconditional call forwarding number, it forward directly to the unreachable call forwarding number, which is set to the voice-mail number, and the caller is directed immediately to voice-mail. the way to fix this is to change the call forwarding for 'unreachable', but as i mentioned earlier, you can't do this yourself; i have tried with both the phone settings and the mmi number (which btw is very hard to find), both return some kind of error indicating that it cannot be done. so, you need to call at&t and tell them, very specifically, that you would like to set *only* your 'forward on unreachable' to the number that you actually want to forward to. now, when the caller calls the number, if you have set unconditional call forwarding, or you turn off your phone, or you set it to airplane mode, or you take the sim out and go to another country, your calls will be correctly forwarded directly to the 'forward on unreachable' number, which is correctly set. i have done this, and it works perfectly...it's easy to test, you just need to put your phone in airplane mode.  to any google voice users, i have set mine to a google voice number, and it works perfectly. now, if i have wifi access in another country, or i put another sim in my phone that has internet, i will be able to answer calls that come in to my at&t wireless number on my google voice number. beware that the level 1 staff at the 611 line are completely clueless about this and they will try to send you a link to the set of instructions to do it yourself...they don't work; you need to insist that you want them to do it, and try to talk to one of the wireless experts who can actually set the correct call forwarding at their end. be prepared with your imei number, they asked me for it for both lines.
hello @oscarmorton94,in regards to texts, try the following:1) turn off imessage (settings > messages)2) restart your phone (by pressing and holding the on/off button)3) tap settings > phone > my number and confirm that it is correct.4) if it is not correct, please enter the correct number5) turn imessage back to on (settings > messages)6) finally, go to settings > messages > send & receive and see if the correct number is displayed under “start new conversations from:”.for the coverage, it sounds like the coverage in your area isn’t as good. contracts purchased from us come with a 30-day change of mind, and 14-days via carphone warehouse.if you’re still in the returns window, we can help process a return.i’ll pm you anyway incase you wish to go through with this.mohammed ALWAYS call this in. For some unknown reason Samsung on most models doesn't have an option to turn that off.

You have choices to make here. Call it in and confirm then decide if the set is going back as its design doesn't work for you. I have this problem too. I've tried many way too fix it but my phone still have this problem. howdy @moufflon

does your phone allow you to define which sim your phone would use by default for data?

they might be an issue with a dual-sim phone, or a setting there within.

could you try removing the o2 sim, deleting the o2 apn settings and trying if the sim is working for data then?


kevin what you’re gonna want to do then is, is to order the home phone now with a random number, and then once you’re closer to the date that you want to cancel with bell, login to self serve and request to have the number ported. hey there 😊 sorry for the delay! this might be a bit tricky as we are unable to ship you a sim card that you would need to use our service there.if you are able to have someone visit one of our stores and purchase a sim starter kit ($20) and activate it on our $40/month simply prepaid plan then ship you the sim card, you can place the sim in any t-mobile compatible phone and use our service. just so you are aware, it is $1.49/min for incoming and outgoing calls and text messages are $0.50 to send, $0.10 to receive so you will need to add extra funds to your account to be able to use your service there. also, please be aware that while the plan comes with 3gb of high-speed data, you will not be able to use data services while roaming in another country with this plan. you can’t move a sim from an older (moto x1, x2, g1, g3, e1 or e2) to a new phone. you’ll need a byod sim: [bring your own phone to republic! | republic wireless](https://republicwireless.com/bring-your-own-phone/) Please refer to the following FAQ regarding your phone's unlocking :
