In today's rapidly growing global business landscape, the importance of account systems has reached new heights. Regardless of whether you're registering for TikTok, Telegram, Google, or setting up WhatsApp Business customer service systems, having a stable and reliable international mobile number for long-term account management is crucial.
Moreover, users might encounter lags during the process of setting up their number, easily facing restrictions due to transient identity verification codes or being limited in certain scenarios. In this context, Cloud Number emerges as the most effective solution for international service providers.
Cloud Number is a technological service enabling users to utilize mobile numbers on the cloud, managing SIM cards or virtual numbers remotely. Users can conveniently receive verification codes online, which are used for registration, confirmation, and long-term number management.
Key Features:
The applications of Cloud Number are quite extensive, especially suitable for cross-border and multi-account users, including:
(1) Registering/Logging into International Platforms
When registering with foreign apps, some verification codes may be undeliverable due to localized restrictions or simply due to network instability, requiring international number codes instead, further amplifying operational costs when using physical SIM cards.
Using a Cloud Number to register an account ensures the authenticity of that international number, making number acquisition and management more convenient.
Generally speaking, Cloud Numbers support registrations for TikTok, Telegram, Facebook, WhatsApp, Google, Amazon, PayPal, and other platforms.
(2) Multi-Account Operational Management
For users looking to operate multiple international numbers, utilizing multiple Cloud Numbers significantly enhances operational efficiency while being easier to manage.
Each Cloud Number is independent, integrating seamlessly with device IP addresses and geographical locations, enabling high reliability, supporting media campaigns, ad placements, internal information number testing, and cross-border group setups.
(3) International Business Support
If you require WhatsApp Business for customer connections or if you're creating Telegram channels or services, Cloud Number can alike serve as a front-facing number, eliminating the need to worry about initiating number or device shutdowns.
| Cloud Number | Physical SIM Card | |
|---|---|---|
| Usage Method | Cloud connectivity, allowing remote operations through a management platform | Requires inserting a physical SIM into the device, needing manual operations |
| Usage Difficulty | Easy to use online, immediate availability | Requires purchase and sending to the user, affected by logistics/geographical limits |
| Cost | Monthly rental or pay-per-use model; platform-based operational costs | Physical card + shipping costs |
| Long-Term Stability | High, allows long-term stable number management | High, requires physical device to be powered on or SIM to be replaced when not used; shutdown requires substitution |
| Account Registration Pass Rate | High | High |
| Multi-Account Management | Cloud Phone + Cloud Number combination allows complete independence | Requires multiple cards and multiple devices or SIMs, higher cost and more complex management |
| Receiving Verification Code’s Capability | Supports SMS verification codes, auto-forwarding to the cloud | Supports SMS, but relies on the user's physical device |
| Privacy Protection | No physical SIM required, protects personal information | Requires a physical SIM, potential for personal information breaches |
| Applicable Scenario | Long-term operations, cross-border multi-account management, international registrations and transactions | Practical for long-term use of physical numbers, SMS verification, travel usage |
On cross-border operations, overseas phone numbers are often an unavoidable necessity. Whether for registering social media accounts, verifying logins, or building large-scale account matrices, traditional physical SIM solutions suffer from limited card resources, complex management, and cumbersome operation.
To address these challenges, DuoPlus has launched the all-new “Cloud Number” feature — enabling completely cloud-based acquisition and use of overseas phone numbers, helping global users build, manage, and maintain their account systems with greater efficiency.
01 Easier Purchase: Instantly Available Online

On the DuoPlus platform, users can directly select the desired country and platform type to purchase and activate numbers online. No physical devices or manual review required — activation takes effect immediately.
02 Cloud-Based Message Reception: Centralized and Worry-Free

After purchase, each account is assigned a unique cloud number that can receive verification codes directly in the cloud. Users can check and copy codes in real time from anywhere. The unified dashboard allows batch viewing, categorizing, and managing all numbers easily — greatly improving multi-account management efficiency.
03 Authentic User Experience: Stable and Secure

The DuoPlus Cloud Number integrates seamlessly with DuoPlus Cloud Phones, allowing direct registration and login on TikTok and other overseas platforms.
With an independent, clean Android cloud environment and multi-layered simulation settings, DuoPlus ensures device authenticity and stability. Combined with carefully selected long-term overseas number resources, the system mimics real user behavior more closely, effectively increasing anti-blocking performance and account longevity.
Taking DuoPlus Cloud Phone SIM card as an example, it essentially explains the workings of a Cloud Number:
Currently, DuoPlus Cloud Number can only be used for receiving verification codes, not supporting sending SMS or making calls.
1. Can Cloud Number be registered for WhatsApp/TikTok?
Yes, but attention must be paid to the effectiveness of the Cloud Number, concurrently requiring the number's host country and registration zone to be consistent.
2. How does the Cloud Number integrate with mobile device services?
Each Cloud Phone integrates independently via IP and device guidelines, allowing the use of different Cloud Numbers to register accounts while not being subject to local platform connection issues.
3. Can Cloud Number support long-term business number operations?
Yes, DuoPlus Cloud Number supports long-term subscriptions, covering account logins, secondary verification scenarios, providing even greater benefits for business continuity.
