        Hi Ben, I am traveling to Hong Kong in July and then again in October. How long this deal will last for? Can I buy it now and activate it after 2 - 5 months later?

        Your website has a terms and condition, which says the eSIM has to be activated within the validity period. But it doesn’t specify the validity period.

        • AdModnar on 03/05/2025 - 09:10

          also says:
          "Aussie Based assistance from 8AM-10PM AEST to keep you connected, anytime, anywhere."

          and
          "Our support team is here 24/7 to help you troubleshoot. Just reach out via email or live chat, and we’ll get you connected."

          should that second one be 'here 14/7'?

          Edit: I got a response from the support team :

          the eSIM will remain valid until october if you purchase it now. It only starts to count once installed.

    • AssociatedBen-TeamFlex @ Flex Mobile on 03/05/2025 - 00:04

      We can do Regional/Global packages which are available on our site.
      However the prices aren't as low as we'd like at this point. We're working with our providers to lower the pricing for these packages.

  • Willyslicks on 02/05/2025 - 23:39

    Wow looks really cheap, what's the catch?

    • AssociatedBen-TeamFlex @ Flex Mobile on 03/05/2025 - 00:07

      No catch here!
      We work closely with network providers to get the best pricing possible.

  • sistermay on 02/05/2025 - 23:49

    What does 20GB 30 days mean ? Would the 20GB data be spread over the 30 days period and each day I am only allowed to use 0.66GB or I can use it till data exhausted as long as it is within the 30 day period ??

    • AssociatedBen-TeamFlex @ Flex Mobile on 02/05/2025 - 23:59
      +4

      20 GB / 30 days means you will get a total of 20 gigabytes of data that’s valid for 30 days from activation. There is no built-in daily allowance of 0.66 GB you can use the full 20 GB any way you like (for example, 5 GB one day, 1 GB the next, none the day after), as long as you stay within that 20 GB cap and the 30-day validity window. Once you hit 20 GB or the 30 days expire, your data allowance ends (unless you top up or renew).

        Why is an “Aussie” site in USD?

        • AssociatedBen-TeamFlex @ Flex Mobile on 03/05/2025 - 01:31

          Our prices are in USD because we serve a global customer base, and USD is the most widely accepted currency for international transactions. It also helps keep things consistent across different countries we operate in, especially since our eSIM service is travel-focused.

          We're working on a feature that'll auto convert the currency based on the users GEO location.

            • sween64 on 03/05/2025 - 08:13

              @ozilicious: I'd want to select the currency that is cheapest and pay with a fee-free credit card. I assume Flex is paying the network providers in USD so I'd choose USD. Both views are valid. Flex just needs to provide options.

    Update from Flex Mobile:

    We’ve had a big spike in orders come through all at once, and it’s been a great learning experience for the team.

    Our automated provisioning system handled most of the load well, but it did skip a beat occasionally so we’ve had to jump in manually to sort a few orders out. We're already making improvements to strengthen the system and reduce friction going forward.

    We’re also working on rolling out more automated support to help you get answers faster without having to wait in a live chat queue.

    That said, response times may vary for now. Due to the current demand, we’re temporarily reducing our support hours slightly so our team can focus and work together during peak periods to handle the volume more effectively.

    So please bare with us as we're fine tuning our systems and processes.

    Thanks again to everyone who’s ordered, reached out and given feedback. We’re a small team building something we care about, and this kind of demand is helping us improve fast.

    Cheers,
    The Flex Mobile Team

  • Dyl on 03/05/2025 - 03:05

    Do they route back to Australia or via local networks? I've found most eSIMs route via the companies home country not local break out. Makes them useless for anything ping sensitive.

    • AssociatedBen-TeamFlex @ Flex Mobile on 03/05/2025 - 03:09
      +1

      Hey, so our eSIMs currently have breakout points globally this being Hong Kong, Vietnam, Europe and soon to be other locations.
      We're working with our network partner to quickly establish more POPs (Points of Presence)

      • Dyl on 03/05/2025 - 03:50
        +1

        Good to hear, sucks getting eSIMs only to find out they're 300ms+ ping.

        Any chance of adding global ones in the future, ie for use in most countries? I typically only buy eSIMs for transiting and buy a local SIM when I land, so multi-country is best even if it's only 1GB.

    • cooni on 03/05/2025 - 08:20

      That's a really strange thing (and I'm not doubting it's truth)

      If the traffic needs to go to an international POP (I'm sure over "the internet") why not just send/receive it directly from where you are?

      • Dyl on 03/05/2025 - 16:45

        It’s a known thing with roaming, they need local break out support added (which requires deals with local providers) or it routes back to the SIMs home country. Alternatively they set them up aa single country SIMs and IP bandwidth is apart of the contract, then there’s no issue.

        It’s especially applicable for multi country SIMs as it requires the addition of specific local break out technology (available under 5G specs) which is setup separately to roaming access, otherwise all traffic is via the “home” network (which for a regional eSIM could be anywhere)

        Cheap eSIMs are usually the worst for it because it’s simply cheaper not to negotiate contracts for every single country you sell SIMs for. Roaming contracts you can very easily purchase wholesale access, but local break out and/or local IP bandwidth is harder to access and they’ll usually need to research providers for each individual country.

        Same issue is present with general roaming - no Australian provider has local break out roaming despite 5G supporting it for literal years now.

  • NorthPort on 03/05/2025 - 09:45

    G'day, tried accessing your support portal last night and this morning, but no luck.
    In in Thailand and just bought the basic 7 day plan.

    I've added the esim and believe it is active, however it does not appear to be working for calls or data.
    It shows an R next to my carrier in the top bar of my Motorola edge 50 neo. I've turned off my Australian physical SIM and an just using the esim (which refers to the esim as Carrier). Any help appreciated.

    Update. If I select roaming then data does work. Should the esim use roaming or natively connect to the local carrier?

    • Mugsy on 03/05/2025 - 10:08
      +1

      Depends on who is providing the service.

      For example, many China esims are provided by Hong Kong based telcos. It helps circumvent the great firewall of china.

      No idea what the arrangements for Thailand would be but I'm guessing it's a provider outside of Thailand.

      Hey also following on from that.

      When using your eSIM, data roaming needs to be enabled to ensure it works correctly.

      Any questions feel free to reach out :)

        Thank you very much for the response. Works great!

    • YetAnotherChris on 03/05/2025 - 18:35

      It's a Singapore or HK sim with a roaming agreement with a local carrier. It needs roaming enabled.

      If you want a local sim go to an AIS or DTAC store and get an esim, or get a 10-day/50GB DTAC tourist esim (doesn't expire, just has a 10 day data pack) on the Nomad app for $7US. You can then reload it using an app or at 7-11 for a few baht per day.

  • at91 on 03/05/2025 - 10:22

    My parents are going to the US next week. They are very low-tech, and if I buy the United States 10GB 30-day plan, how would I activate it for them? Should I activate the SIM on the day they check in at the airport?

    Once they arrive in the US, will the SIM automatically work for 4G data?

    • AssociatedBen-TeamFlex @ Flex Mobile on 03/05/2025 - 10:56

      If your parents aren't tech-savvy, the easiest way is to install the eSIM for them before they leave — ideally on the day they check in at the airport or just before.

      Once they arrive in the US, they'll have to go into there settings and enable data roaming (If you'd like to do this for them beforehand this is fine). It will automatically connect to a US 4G network and start working. The 30-day plan will begin from when it first connects.

    • YetAnotherChris on 03/05/2025 - 18:41

      IMEI registration is required only after 90 days. Your phone will stop connecting and you'll need to go to a carrier store your passport and visa.

      If Australians haven't left by then they'll be annoyed at you for other reasons.

  • b0b0 on 03/05/2025 - 10:58

    Is pre-activation days on the page referring to the lead time we have to add the esim before travelling?

    E.g. for Malaysia, 180 days - does that mean I can buy this esim and use it in September?

    • AssociatedBen-TeamFlex @ Flex Mobile on 03/05/2025 - 11:15
      +1

      @b0b0
      Yes, the "pre-activation days" simply means how long you can wait before activating the eSIM after purchase.
      So for Malaysia, the 180 days means you can buy it now and activate it any time within the next 180 days

    Hi Ben, thanks for posting this deal!

    Just wanted to clarify—are the eSIM plans listed here standard data-only eSIMs, or do they also support traditional voice calls and SMS services (not just VoIP)? It would be helpful to know whether these plans come with a mobile number and support for incoming/outgoing calls and texts, or if they're purely for data use only.

    Appreciate your clarification!

    • AssociatedBen-TeamFlex @ Flex Mobile on 06/05/2025 - 01:34

      Hey,

      The eSIM plans listed are data-only, so they don’t include traditional voice calls, SMS, or a mobile number. They’re designed primarily for internet access while travelling perfect for things like maps, messaging apps (like WhatsApp), social media, and browsing.

      These details can also be found on all of our eSIM product descriptions.

    Purchasing and activation was fast and painless, from ordering to being connected took less than 5 minutes.

    Looks like the traffic is routed to Poland, which unfortunately meant my actual browsing experience and network speed is very slow - eg. At least a few seconds wait to open this webpage. However for navigation, messaging (hopefully not sending too many photos), contactless payment etc has been flawless.

    If your internet use demands are not high, this is fantastic for a low price.

      Thanks heaps for the feedback and for grabbing a plan with us!

      Great to hear activation was smooth and that core things like maps, messaging, and tap payments worked without a hitch, that’s exactly what we aim for.

      At the moment, our USA plans route data through various European locations (like Poland), which helps us keep things affordable, though it can impact browsing speed. We’re actively working with our network partners to explore a US-based data exit point to improve performance for future travelers.

      Really appreciate you sharing your experience — it’s super helpful for others and for us as we continue refining things.

      If you’ve got a sec, we’d love it if you could leave us a quick review here:

      Interesting. Has anyone used in Japan yet? Wondering if it will have the same issue…
