    Sure you got 2 numbers but no matter what number someone calls you on how does the phone user know the difference between personal or business calls?

    What happens to whatsapp? Would I be able to use it as normal or will I have to update my australian number to use whatsapp

    For the first reason you can simply port your number to your new SIM, which is really easy

  24. asimo on April 22, 2021 at 12:48 am

  25. JOEL DONAHUE on April 22, 2021 at 12:49 am

    Wich Sim slot do I need to use for SIM CITY ?

  26. mss burr on April 22, 2021 at 12:50 am

    All I want is to find the sim card manager in the Samsung A11
    I have searched YouTube with no luck… if you know can you please upload a video showing where to locate the Sim manager..

  27. Frazzle on April 22, 2021 at 12:50 am

    So you can buy a landline number sim for business purposes and still receive calls to both Sims?

  28. Dove Paradise on April 22, 2021 at 12:52 am

    So many questions…
    1) Does is tell you which line the incoming call is coming from? If it’s on silent I won’t hear the different ringtones
    2) Like someone else asked, how do you differentiate between say business & personal line incoming texts
    3) I see that you can set the default calls from a SIM card. What if I use both lines frequently? Is there an option while dialing to always switch like in text?

  29. Chris Kennedy on April 22, 2021 at 12:52 am

    good video ty. Btw feel like the color hue is a bit yellow in this lol you look like a simpson 😛

  30. jagz jagz on April 22, 2021 at 12:52 am

    Now the real question 😁

    Can you ring/text from your 1st Sim number to your 2nd number 🙄

  31. Vedat Sözen on April 22, 2021 at 12:52 am

    What about photos and videos ? Can 2 people use one phone with separate sim cards ?

  32. allsports now on April 22, 2021 at 12:52 am

    thanks

  33. 2b02b on April 22, 2021 at 12:56 am

    What happens with different wassup group when receiving or making calls?

  34. Robert L on April 22, 2021 at 12:57 am

    Yeah but anyone who calls how do you know if it’s for personal or business?

  35. Richard Sleep on April 22, 2021 at 12:57 am

    Yes thanks for this very helpful and straightforward explanation.

  36. Jerryatic on April 22, 2021 at 12:57 am

    grande Milei

  37. Lizzz on April 22, 2021 at 12:57 am

    I know this is a stupid question 😅, but can I use one sim card in a dual sim card phone?

  38. Aidan Gonçalves on April 22, 2021 at 12:58 am

    So if I’ve been on a contract for a while with Vodafone and I’ve got a dual SIM, can I buy another sim from same network and still use it for like going on holiday such as unlimited data on that new SIM?

  39. Conor wK on April 22, 2021 at 12:58 am

    Nice video man. Very helpful and to to the point

  40. Richard on April 22, 2021 at 1:01 am

    Wow that’s so good. I was told you can’t have both active at the same time especially in Australia. But this is exactly what I need for work number plus personal number.

  41. Kmill Kazor on April 22, 2021 at 1:01 am

    High quality & very informative video. Thanks a ton 😄😁

  42. tom frost on April 22, 2021 at 1:01 am

    Fantastic about to ask if I can use both sims at the same time and then it was covered, like below all the facts no waffle

  43. Bryce Oslie on April 22, 2021 at 1:02 am

    Thanks

  44. Zaruras on April 22, 2021 at 1:03 am

  45. magzire on April 22, 2021 at 1:06 am

    what about battery life?

  46. Karen Bailey on April 22, 2021 at 1:06 am

    Very informative thanks 👍🏻

  47. Heather and Maurice Carthew on April 22, 2021 at 1:07 am

    What if when you put a cards from 2 companys and one will not show?

  48. Single To Taken TV on April 22, 2021 at 1:08 am

    Love your video. What would happen if you place one sim an leave the other sim card slot blank? Will it still work like an ordinary phone?

  49. 5183adam on April 22, 2021 at 1:11 am

    With duel standby. If my phone is not being used. Basically sat doing nothing. will it ring regardless of what number is rang from someone. Or will only the activated aim be available

  50. Bianca Brits on April 22, 2021 at 1:14 am

    Thank you, this is so helpful and informative, am going to try combine work and personal SIM cards in Samsung Galaxy S7 Edge and hoping it works as easily as your video 🙂
