What is IoT Connectivity & eSIM?
Dollu IoT connectivity gives device makers, solution providers and enterprises a single global SIM that attaches to the best available mobile network wherever a device is deployed. Our multi-IMSI SIM carries several operator identities and switches between them automatically, so a device shipped from a factory in Shenzhen can power up in São Paulo, Lagos or Leeds and connect without a local contract, a local SIM or a truck roll. Coverage spans more than 190 countries and territories on 2G, 3G, 4G LTE, LTE-M, NB-IoT and 5G, with the radio access technology chosen per device profile.
For products that need remote provisioning, we supply eUICC-capable SIMs - plastic 2FF/3FF/4FF, industrial MFF2 solder-down and iSIM on supported chipsets - managed by an SM-DP+ platform compliant with GSMA SGP.22 for consumer devices and SGP.32 for IoT. Profiles can be downloaded, swapped or deleted over the air, letting you change operator strategy after devices are in the field, localise connectivity to meet permanent-roaming rules, or move an entire fleet to a new carrier without touching a single unit.
Everything is controlled from our connectivity management platform. Activate, suspend and retire SIMs, set data caps and network policies, group devices by product or region, and watch sessions, signalling and usage in real time. The same functions are exposed through a REST API and webhooks so lifecycle events flow straight into your own back-office, ERP or device-management stack. Private APNs, static IPs and IPsec or MPLS breakout keep device traffic off the public internet where the application demands it.
Commercially, we keep IoT simple. Pooled data plans share an allowance across every SIM in an account, so a few chatty devices do not push you into overage while quiet ones sit idle. Rate plans are priced per zone, with low-bandwidth NB-IoT and LTE-M tariffs for sensors and metering, and higher-throughput LTE and 5G plans for routers, cameras and vehicles. Whether you are running 500 pilot units or 5 million connected products, you get one contract, one invoice and one 24×7 NOC.
Why choose Dollu for iot connectivity.
The advantages of buying from a carrier that owns its network, interconnects and operations - rather than a reseller.
Ship one SKU worldwide
A single multi-IMSI SIM covers every market you sell into, so you build one product variant, hold one SIM inventory and stop negotiating with an operator in each country.
Change operators without touching devices
eUICC profiles are downloaded, swapped or removed over the air, so you can localise connectivity, cut cost or respond to a permanent-roaming restriction years after deployment.
Automate the whole lifecycle
Every action in the portal is available over API - activate SIMs at manufacture, move them to live tariffs on first attach, suspend on non-payment and retire at end of life.
Predictable cost at scale
Pooled allowances, per-zone pricing and hard data caps mean a handful of misbehaving devices cannot generate a surprise bill at month end.
Traffic that never touches the public internet
Private APNs with static addressing and IPsec or MPLS breakout to your cloud or data centre keep telemetry and firmware traffic isolated and inspectable.
Capabilities in detail.
Everything included with IoT Connectivity & eSIM - the platform features, options and controls you get from day one.
- 01
Multi-IMSI global SIM
Multiple operator IMSIs on one SIM with rules-based selection by country, radio technology and cost; automatic fallback if a network rejects the attach; steering lists updated over the air.
- 02
eSIM / eUICC and remote SIM provisioning
GSMA-compliant SM-DP+ for consumer (SGP.22) and IoT (SGP.32) profiles; bootstrap plus operational profiles; profile download by QR code, activation code or eIM for headless devices.
- 03
Form factors for every design
2FF/3FF/4FF plastic, MFF2 solder-down, industrial-grade SIMs rated for –40 °C to +105 °C, high-endurance memory for frequent-write applications, and iSIM on supported chipsets.
- 04
Radio access across LPWA and broadband
NB-IoT and LTE-M for battery-powered sensors, 4G LTE Cat-1 and Cat-4 for routers and gateways, 5G NSA/SA where networks support it, with 2G/3G fallback in markets that still run them.
- 05
Connectivity management platform
Real-time SIM status, session and usage views, bulk actions, device grouping and tagging, alerts on data thresholds, IMEI lock and unusual-usage detection, with role-based access for your teams and customers.
- 06
APIs and integrations
REST API and webhooks for provisioning, usage, diagnostics and billing data; SDKs and Postman collections; connectors for AWS IoT Core, Azure IoT Hub and common device-management platforms.
- 07
Private networking
Dedicated APNs, static private or public IPv4/IPv6 addressing, RADIUS integration and IPsec or MPLS breakout into your VPC or data centre; SMS-to-device and OTA firmware channels.
- 08
Data plans and billing
Pooled and per-SIM plans, zone-based pricing, NB-IoT and LTE-M low-usage tariffs and multi-year committed rates; invoices and CDR-level usage exports by API or SFTP.
How it works.
From first conversation to live traffic - a tracked, engineer-led onboarding with a named owner at every step.
- Step 01
Scope the deployment
Tell us your device profile, target countries, radio technology and expected data per device. We return coverage maps, a recommended SIM form factor and a plan proposal within two business days.
- Step 02
Test with sample SIMs
We ship evaluation SIMs or eSIM profiles with a sandbox account so your engineers can validate attach times, throughput and API flows before you commit.
- Step 03
Integrate and provision
Connect the API to your manufacturing or fulfilment system, set up the private APN and alerts, and pre-activate SIMs so devices connect on first power-up.
- Step 04
Scale and manage
Monitor the estate from the platform, roll out eSIM profile changes over the air and let your account manager tune plans as usage patterns settle.
Who uses this and why.
Typical deployments across carriers, enterprises, platforms and contact centres.
Smart metering and utilities
NB-IoT and LTE-M SIMs for electricity, gas and water meters that must run for years on battery in basements and cabinets with weak signal.
Payment terminals and retail
Multi-IMSI SIMs and a private APN for POS terminals, vending machines and kiosks that need PCI-aligned, always-on connectivity in every store.
Connected health devices
Remote patient monitors, glucose readers and dispensing devices that ship worldwide and must connect on unboxing without patient setup.
Industrial and OEM equipment
Machine builders embedding connectivity at the factory for telemetry, predictive maintenance and remote diagnostics on assets sold into 100+ countries.
Security and video
LTE and 5G plans with pooled data for CCTV, alarm panels and body-worn cameras that need burst bandwidth and reliable failover.
