eSIM
We are a global IoT MVNO, providing the UK’s first multi-network eSIM to our customers. You can order multi-network roaming connectivity, delivered via GSMA-compliant, removable or embedded eSIMs.
Our eSIM provides access to over 450 networks in over 190 countries. Wherever the
eSIM is in the world (local regulations permitting), it is always roaming. eSIM facilitates a
device to connect to the strongest available network. Multiple steering options are also
possible e.g. prioritising the lowest cost network in specific countries or preferring one
specific network over another.
We have deployed a UK-based, resilient MVNO mobile core network, with global connectivity to over 450 networks in over 190 countries
and local connectivity with all four UK mobile networks. UK-based interconnects and breakout ensure the traffic stays in the UK. Traditionally
MNO roaming SIM traffic is routed back via a home network, outside of the UK, increasing latency and the uncertainty of prioritisation,
security, local legislation, and steering by the operator
Our eSIMs provide reliable, flexible and cost-effective mobile data access. The solution is suitable for any M2M/IoT application that requires
wireless Internet or private network access virtually anywhere in the world. The solution is designed to be suitable for all types of applications,
from low consumption IoT solutions through to high consumption mobile broadband solutions
Our eSIM (eUICC) is available in multiple form factors: You are able to order triple-cut, industrial, M2M, eSIM cards (Mini SIM – 2FF, Micro SIM
-3FF, Nano SIM – 4FF) or embeddable industrial eSIMs (MFF2)
eSIM is a standard set by the GSMA, the association representing mobile network operators worldwide. It is a new technology which means
that a SIM can hold multiple mobile profiles simultaneously and can be re-configured ‘over the air’ (OTA) with new profiles or profile selection
rules. We use of this technology means that resellers can choose whether to deliver mobile data solutions that are optimised for best
coverage or for best cost, whilst retaining the flexibility to change this preference in the future
An issue for manufacturers selling their products in different countries has been the
need to maintain multiple SKUs. This is because they have had to use SIMs from
different operators based on the territory they are to be sold in. No single mobile
network operator can provide the optimal solution for all countries but eSIM solves this
problem.
Pay Per Zone eSIMs
With Pay Per Zone eSIMs, pricing is divided into five zones from EU countries to worldwide. End-users only pay the higher zone rate when
using the higher rate networks and revert to a lower zone rate when in lower rate networks. Partners can view usage in Mobile Manager and
bill end-users on per zone rates.
Un-steered and network agnostic
The service is completely network-agnostic and by being un-steered, we offer the best possible service in any location.
Re-programmed ‘over the air’
End users do not want to manage and fund engineers swapping out SIM cards in every device. They also do not want to be locked into pricing, due to the cost of switching.
Pay Per Zone eSIMs
With Pay Per Zone eSIMs, pricing is divided into five zones from EU countries to worldwide. End-users only pay the higher zone rate when using the higher rate networks and revert to a lower zone rate when in lower rate networks.
Key features and potential benefits
| Feature | Potential Benefits |
|---|---|
|
Global |
Multiple mobile network operators MNO with all 4 UK networks included and access to over 450
networks in over 190 countries worldwide. |
|
Configure Over The Air (OTA) |
Mobile profiles and profile selection rules can be loaded and updated over the air. This enables a level
of flexibility that simply cannot be matched by standard mobile operator SIMs. |
|
Secure |
The GSMA eSIM standards are built on robust foundations that prevent any manipulation of the
mobile profiles being modified by unauthorised parties. |
|
Industrial-grade |
Our eSIMs are M2M industrial grade and suitable to be used in extreme environments (e.g.
temperature, vibration and humidity) |
|
Cost effective |
Pick the tariff required based on the amount of data the customer needs and the country (or
countries) that the SIM will operate in. No more unexpected roaming charges to worry about. |
|
Manageable |
Our eSIM is provisioned and managed via Mobile Manager portal, that provides a simple but
powerful interface, enabling our customers to activate SIMs, monitor usage, setup alerts, add
bolt-ons and cease services. Furthermore, you can optionally setup Mobile Manager so that your
own end-users can log in to monitor and manage their own estate of SIMs. |
|
Simple |
Site surveys to determine which networks are available are expensive and time-consuming; one SIM
connects to multiple networks in most countries. |
|
Future-proof & cost-saving |
No need to go to the trouble and expense of a truck roll to swap out an estate of eSIMs at the end
of a contract if the original deal is no longer the best fit. |
|
No ‘home’ network |
eSIM is unlike most other UK-based MVNOs in that we do not have a ’home’ network. This
means that by default our eSIM is unsteered. In practice this means the SIM will connect to the
strongest available network and the device is then able to switch to a stronger signal should one
become available. Custom steering options are also available. |
|
UK breakout |
Foreign operator roaming SIMs deliver un-steered, multi-network connectivity. All traffic on these
SIMs is routed back to the home network from the UK resulting in increased latency and the UK
user being geo-located in a foreign country. This is not normally an issue and Jola has sold
thousands of Dutch and Irish roaming SIMs using this model.
Our roaming eSIM is different as all traffic breaks out of Tsav’s core network in the UK resulting in a superior performance when compared with foreign operator roaming SIMs in the UK. |
|
Wide range of options |
Tariffs ranging from 10MB to 200GB with data bolt-ons and pooled data options also available. |
|
New Mobile Technologies |
New, exciting mobile technologies are always under development. Examples include 5G, LTE-M and
NB-IoT. When these new technologies are made available to roaming partners then the Tsav eSIM
will support them. There is no faster way to gain access to these technologies, across multiple
networks, than by using eSIM due to its inherent ability to be reprogrammed to support new
networks and new technologies. |
|
Private APN |
For partners wanting a secure mobile data solution, layer 3 Private APN delivery is an option. |
|
L2TP Option |
For partners wanting full control over IP addressing and routing, L2TP delivery and framework is an
option. |
|
Fixed IP eSIM Option |
For partners wanting un-steered roaming coverage on all 4 UK mobile networks, Fixed IP eSIMs are
available. eSIM Fixed IP is delivered using a true IP address, which does not require static IP
addresses or NAT. Reverse DNS is also available upon request. |
