What is International Roaming Services?
Opening and operating roaming is one of the most complex parts of running a mobile network. Every partner requires an IREG and TADIG test cycle, a signalling relationship, a billing agreement, a data-clearing setup and ongoing quality management. Dollu’s international roaming services take that load off MNOs, MVNOs and IoT connectivity providers. Through our roaming hub you connect once to Dollu and gain access to a footprint of more than 600 partner networks in 190+ countries, with commercial and technical relationships managed centrally rather than one bilateral at a time.
The hub sits on our GRX/IPX and SS7/Diameter signalling platforms and carries every generation of roaming: CAMEL and SS7-based 2G/3G, Diameter for LTE and VoLTE with S8HR or LBO models, and 5G roaming over N32 through our SEPP for both SA and NSA networks. Steering of roaming - signalling-based and OTA-based - directs your outbound subscribers onto the partner networks that give you the best combination of cost, quality and technology, with per-country rules, blacklists and campaign scheduling that you control from a portal.
Behind the scenes we run data clearing and financial clearing. TAP 3.x and BCE records are validated, converted, rated and exchanged with partners; disputes, RAP files and stop-loss thresholds are handled by our clearing team; and net settlement is calculated and remitted in your currency. Roaming testing covers IREG, TADIG and end-to-end regression tests for new services such as VoLTE and 5G, executed from our lab and from physical test SIMs placed in partner markets.
Everything is visible in near real time. Roaming analytics track inbound and outbound roamers, attach and registration success, data session performance, VoLTE call quality and revenue by partner, and alert your team when a route or partner degrades. For IoT connectivity providers and MVNOs without their own agreements, sponsored roaming lets your SIMs roam under Dollu’s IMSIs and agreements, extending your footprint immediately while you decide which markets warrant your own bilateral deals.
Why choose Dollu for roaming services.
The advantages of buying from a carrier that owns its network, interconnects and operations - rather than a reseller.
Faster market opening
Skip months of bilateral negotiations. Through the hub, a new partner network can be commercially and technically live for your subscribers in weeks rather than quarters.
Lower wholesale roaming cost
Steering pushes outbound traffic to preferred partners and negotiated discount agreements are enforced automatically, so inter-operator tariff spend falls without harming user experience.
Latest technology, day one
VoLTE and 5G SA roaming are already built and tested on our platform, so you launch new roaming services without standing up your own SEPP, DRA or test infrastructure.
Revenue and fraud protection
NRTRDE feeds, high-usage alerts and TAP validation catch fraud and billing errors early, protecting inbound revenue and stopping outbound bill shock.
Complete operational visibility
One dashboard shows every partner, every technology and every KPI, backed by a roaming operations desk that watches your traffic 24×7.

Financial clearing and settlement
Multilateral netting, invoicing, dispute management and settlement in USD, EUR, GBP or INR; credit-risk monitoring and stop-loss thresholds per partner.
- 05
5G and VoLTE roaming
5G SA roaming over N32 through the Dollu SEPP with PRINS/TLS security; 5G NSA over existing LTE roaming; VoLTE roaming with S8HR and LBO models, IMS interworking and emergency-call handling.
- 06
Roaming testing
IREG and TADIG test execution and reporting; end-to-end regression for VoLTE, 5G and IoT profiles; physical test SIMs and remote probes in key markets; automated test-case libraries.
- 07
Sponsored roaming
IoT providers and MVNOs use Dollu IMSIs and agreements to reach our full footprint; multi-IMSI and eSIM options; ideal for connected devices without a home MNO relationship.
- 08
Roaming analytics and alerts
Real-time dashboards for inbound and outbound roamers, attach success, data and VoLTE KPIs, and revenue by partner; threshold alerts and weekly partner scorecards.
How it works.
From first conversation to live traffic - a tracked, engineer-led onboarding with a named owner at every step.
- Step 01
Assess
We review your current agreements, traffic and target markets, and model the savings and coverage uplift from hub access, steering and clearing.
- Step 02
Connect
Establish SS7, Diameter and GRX/IPX connectivity to our hub, configure clearing feeds and, where needed, deploy steering and SEPP functions.
- Step 03
Test and launch
IREG and TADIG cycles run against priority partners; VoLTE and 5G profiles are validated; the first wave of markets goes live with your operations team trained on the portal.
- Step 04
Operate and optimise
Our roaming desk monitors quality and settlement daily, adds partners as your footprint grows and reviews steering rules with you each quarter.
Who uses this and why.
Typical deployments across carriers, enterprises, platforms and contact centres.
Mobile network operators
Expand outbound coverage and grow inbound revenue without adding staff, and launch VoLTE and 5G roaming on tested infrastructure.
MVNOs and MVNEs
Get roaming that matches the host operator’s footprint or exceeds it, with independent steering, clearing and analytics.
IoT connectivity providers
Sponsored roaming and permanent-roaming-compliant options for connected devices deployed across dozens of countries.
Travel and airline connectivity
In-flight and travel SIM providers needing dense partner coverage, fast steering changes and low inter-operator rates in tourist markets.
Operators entering new markets
Greenfield or expanding operators who need day-one roaming for launch and want to avoid building a bilateral programme from scratch.
