Is It Possible to Have 2 Sims on The Same Number/Network?

I have an old phone just for hiking trips and exercise, but the constant changing of sim is bother some.

Any way I can just use 2 Sims for the same number?

Comments

  • most likely no.
    if yes, then next person will ask can i have 8 sims with the same number….

    • Why not? It's a fantastic solution to many problems. Google Fi has this.

      • If I call your number, which phone should ring? Or should all of them ring? What happens if you pick up on one? Can you pick up on others? So many questions.

          To be quite fair, all of those are non issue and easily solved. There's multiple systems that can put in place.

          I dunno how Google Fi did it.

          Looks like we have an expert here.

          If I call your number, which phone should ring?
          Answer = All of them

          Or should all of them ring?
          Answer = Yes (as per previous)

          What happens if you pick up on one?
          Answer = The phone that "picks up" takes the call, and the others stop ringing

          Can you pick up on others?
          Answer = No (as per previous)

          So many questions. —-> Only two ;-)

          This is actually entirely possible, and has been used for many years in some countries, for various reasons, including where people wish to save money, or circumvent regulatory systems. The people usually share the "clone" SIMs with other family members, or close friends. It could obviously also be used for the scenario Wonderfool is asking about.

    No because the SIM identifies you to the telco. If they were separated where would a call to the number be routed? You can however forward calls at a cost.

    • Actually, it can be done, but it could also be detected by the Telco if they were looking for this sort of thing.

      If they were separated where would a call to the number be routed?

      I am not exactly sure what you mean, but it isn't a case of anything being "separated", it is achieved by "cloning" the SIM.

      (See my reply above)

      • For sure it's technically possible, but nobody here wants to implement it, because telcos will want to charge more than the market will bear. I think it's more likely that with Internet calls overtaking mobile calls you can eventually get a virtual phone number or URI which can be associated with mobile numbers in various combinations.

        In any case, no telco here will cater to OP's needs. They'll just say use forwarding.

    bet this exists in hollywood movies where they clone sims for infiltration purpose.

    always thought this is possible, just illegal of course.

    It is possible to have the same number on two SIMs, but the Australian systems currently don't officially support the function.

    old phone just for hiking trips and exercise

    If you're hiking and exercising, then your next best option could be to forward your calls from your main number to a prepaid sim (like a 365 day SIM?) in your special old phone. I'm assuming you want to be able to receive calls, but not really make calls during hiking and exercising.

    • "not really make calls during hiking and exercising"

      probably he is expert in multitasking and has 4 hands :D

    • How exactly do you call forward?

      And being able to make calls will be useful too, if possible. A hike means I'll be away from my house for a good half a day.

        Check your provider's instructions. You could suppress caller ID on the cheap phone so people don't get that number.

  • Why not use your main phone for hiking/exercise? I assume it takes better photos etc. If you are worried about damaging it maybe buy a more protective case?

    • Cases doesn't eliminate all damage. Rocky surfaces can still very much damage the screen, no matter what protection you use. Plus, the sand means quicker replacement for screen protector.

    Constant changing of sims? You mean once before you set out, and once when you get back? Doesn't really take that long.

    • +1

      Never said it does take long. Just saying it's bothersome.

  • Amaysim lets you can activate a new sim on their website. I've never tried going back to an old one though … would be interested if this worked.

    Australia really needs a virtual number solution (like google voice), instead of the rubbish we have with port to a new provider every month to get a new sign up bonus.

      Did you seriously just complained about network providers not making an exploit more accessible? LOL.

      • +3

        No - I complained about 'virtual number' functionality being missing from the Australian landscape. It's legitimate technology that has lots of uses.

        Being able to exploit sign up promotions is just a value added bonus!

    It depends, sims 2 and later allows you to control multiple sims but the first sims v1 was only limited to one playable character

    It will depend on your plan, but, in the case of my Telstra postpaid, I can get an extra number/sim tied to my account for $5 a month. Shares the unlimited calls of my plan, but I use it for either my ipad or a 4G Router I have. Between the four people in our household we have a 60GB mobile data allocation, so is plenty (coupled with a TB of home internet quota. Not quite what the OP is asking, but while back, my wife was running a business - Telstra could set up two numbers running to the same phone (on one sim - an Iphone). ANd years ago, when I was with Optus (both as a carrier, and working for them), I actually had a mobile number and a mobile fax number (i.e. a 04xxxxxx number for faxes) - as I recall, i would get a notification of a fax sitting in my mailbox, and could forward it to the nearest convenient fax machine…)

  • Check out equipment for cloning a simcard. I read about it 5-10 years. Vaguely I think it'll cost you, but I think your need was why they were made years ago.
    As said above, you should only switch one on.

    What about diverting calls?

  • You can have multiple sims on one account however as stated before one only for voice and all others for data. So diverson of calls would not work but you could still make calls using VoIP apps. Again depending on your Hike phone that may or may not work but most importantly calls to emergency services may become an issue. Reality today in the marketplace change SIM or get a 365 pre paid one.

  • No No and No. Imagine the conflict of having 2 phones with the same phone number. The system would probably reject both.

    • Yes, Yes, and Yes, actually…

      It has been happening in some other countries for years (see my reply above).

      It also happened to me in Australia, due to the incompetence of my then phone company, and much to my annoyance "the system" did NOT reject anything.
      The same number had been allocated to me, and another woman, with whom I had no affiliation.
      The phone company was of little help, and it took around a month for me to eventually work out what was going on.

  • the concept isn't silly, it just doesn't seem workable in Aus. I have a $1300 iPhone 7+ for everyday use, but carry a $14 android phone during races because of this…….

  • Build yourself a Cisco call manager and implement Single number reach :)

  • I've used multi sim in Singapore before. You just need to designate which one is the primary sim, which will ring first if there's a call. The secondary will ring if no one picks up the secondary.

    I haven't seen this in any of Australia's telco though. Closest you can get is maybe to get a share plan, and setup call forwarding.
