Build It! SIM design

eSIM/SIM card pre-orders are now available nationwide. Use promo FREESIM in the app.
SIM design
Whether electronically distributed (eSIM) or a physical card inserted into your device, the SIM card is used to identify you on our network of networks. In this post, we are sharing some of the progress we've made so far and collecting members' feedback on some of the unique features we are planning.
SIM technology and specs
We are using secure, high-quality SIM/eSIM technology from one of the major SIM card manufacturers. The software on the SIM card can be programmed to do many things, and even small apps can run on it. From a technical standpoint, here's what we're planning.
SIM specs:
- Configured to connect to Multiple Mobile Networks using our network code 302 100
- 3G, 4G/LTE, 5G network compatible
- voLTE support
- Wi-Fi Calling support
- Automatic authentication with AAA (i.e. premium Wi-Fi networks)
- 1MB internal capacity
- Up to 100 important numbers baked in including (WSPs, ISPs, Roadside assistance)
- Built-in NFC support to enable future integrations secured by your SIM
- Over the air updates (SMS/HTTP) will keep your SIM software fresh
- Re-usable (leave, come back, we will always accept your SIM with open arms)
eSIM (embedded SIM)
The easiest and fastest way to subscribe to get connected to dotmobile network is via eSIM. The list of benefits is long, from wastage (we tried to decrease the footprint of physical SIM as best as we could), but also function.It stays on your device for whenever you need it. Secondary line perhaps on iPhone? Apple Watch? All can get connected in an instance. And all that without needing to find a SIM card. Other features are identical to physical SIM. In fact it is the same SIM profile, just delivered electronically and placed securely on an embedded SIM module over the air (eSIM).
Physical SIM card design
The dotmobile SIM card will be available for any phone that does not support eSIM or just a preference thing (we do not judge). You will be able to select the SIM preference during pre-order and when we launch the wireless service in your area.
We’ve spent a considerable amount of time designing the SIM and thinking about the details around security. Multi-network support. And impact on the environment. 90% of SIM card material almost directly goes to the bin.
First order of business was making the most of the physical SIM material our of recycled and biodegradable material, not from plastic. We also got rid of the long 16 number printed on the SIM card (too long to enter), but also a security risk for unauthorized port-outs or sim swaps. You can read more about it here.
Let us know what you think. We are still iterating before manufacturing and any bit of feedback helps.
SIM card feature list:
- SIM code simplifies registering your SIM through the app, 6 letters instead of 16 numbers
- Tri-punch design for standard, micro, and nano SIM card sizes
- QR code opens the app to register the SIM, or download it if not installed
- Made from biodegradable, recycled materials to reduce environmental impact

How to pre order free esim /sim card in case of Android customers?
“FREESIM has expired” Error message when ordering SIM in mobile app as of Aug 31,2021. What is issue?
FREESIM doesn't work anymore and I already paid for the pre-order. I hope we get notified next time, since I didn't get the update of the Pre-Order launch even though, I have all notifications ON in the app.
Tried to "order" the SIM but the app won't register my address.
Is the preordered SIM card no longer free?
How do I order my free sim card
This is a vers good way to promote the service
Will there be an option for international roaming at some point, even if it costs a bit extra? For back when the world is more normal and leisure travel is happening again... That's a con with my current provider. Doesn't matter much now though but in the long run, will it be possible? Without relying on spotty WiFi or buying local Sim? Should anything go wrong at home there is peace of mind in not having to wait till you're in good WiFi again to find out Card design is different, I like it!
I got mine! Too bad you missed the cutoff for founding member.
Hooray! Just ordered my SIM! :)
How long will the biodegradable SIM last?
2 related questions: - can eSim be used on 2 devices at same time (ie. phone and watch can independently use) or can more than 1 Sim be attached to same account - can a physical and eSim have the same registration so that physical Sim goes into older phone and eSim gets installed on watch or IPAD but is under one account
Awesome!!
Can wait to try it!
I wonder if you can swap eSIMs.
Does Dotmobile support VOLTE, and Wi-Fi calling locally and overseas? Do you have to have an approved phone to get VoLTE and Wi-Fi calling working on your device?
eSim is the best
bring on your service
Really waiting for the service. Very excited about the first MVNO. I had the first hand experience of using an MVNO in the UK (Lyca) which disrupted the market there. Just wish it happens the same here when the service launches.
what if i change my smartphone from Android to iPhone?
Will there be an option for eSIM?
It looks more attractive and practical than your typical SIM card!
Pleasantly surprised by how stylish the sim card design is. I'd take it over any of the big 4's sim concepts! Small details always add to the user experience, I'm glad you're not discounting them
Will you have a list of phones supported for esim? I have global LG g7 dual sim phone and some providers support esim and some don't on my phone?
I am looking forward to use your service. When will it be available?
I'm really excited to try out eSIM for the first time!
The sim concept is so cute! Love the organic-looking, "up-cycled" design. Although I'll probably be using an e-sim for my personal use, I think it's great that you're offering a physical option, particularly for older users like my parents (whose phones still primarily relay on sim cards).
Great, so how can I get the physical sim?
Love it. Now I will have to make a decision to get a physical or esim. Thanks
So looking forward to using your service. Thank you for your environmental concerns when designing your SIM card.
Thanks for sharing :)
Love it. Hope you have service in my area!
Can't wait to purchase one of these:o)
Thumbs up for sharing all this info.. good to finally see a telecom provider that is willing to talk/share/discuss with customers. Good to see the progress and eagerly awaiting service launch.
Waiting in anticipation!
Love how much progress you're making. Keep it up!
Really looking forward to launch!
Super excited to check this out
slick design. way to go !

Will I be able to port my current phone number over to DOT
What would happen with eSims, if I want to move devices?
That's a really nice design, dotmobile.
I love that it's re-usable! I've hated in the past that I had an old "travel" sim that was worthless because I had to order a new sim to connect to the same provider. I think I still have a giff gaff sim from my Scotland trip 5 years ago.
Great design! Can't wait for the launch!
I love everything about this idea! I love the reusable cardboard, the sim features (didn't know it could have nfc support) and letters! All super great and can't wait for the launch!
