This table summarizes what HellouOne offers and what Callbell publishes on its site as of November 2026 (see the sources at the end of this page). Whatever we could not find is marked as such instead of assumed.

Callbell's data can change. Before deciding, check its public pages, linked in the sources at the end of this page.

HellouOne and Callbell pricing compared

HellouOne charges in US dollars, by the month, with no lock-in. Starter costs USD 49 with 1 agent (USD 24 without AI), Team USD 190 with 3 agents and a one-time USD 100 setup, Growth USD 490 with 6 agents and Scale USD 690 with 10. The plans with AI include AI messages (2,000 on Starter, 5,000 on Team) and each additional 1,000 AI messages costs USD 30. WhatsApp fees are paid straight to Meta, with a 0% markup from HellouOne.

Callbell publishes its prices in euros (see the sources): 14 € a month per agent on Multi-agent chat and 18 € per agent on Multi-agent chat Plus, plus a custom Enterprise plan for more than 50 agents. Prices exclude taxes. The Plus plan adds dedicated support, advanced statistics, API and integrations.

On top of the per-agent price there are add-ons: 20 € a month for each channel account (WhatsApp, Instagram, Messenger, Telegram, TikTok), the advanced automation builder at 59 € a month and WhatsApp campaigns at 0.02 € per contact reached. Its pricing page does not show a price for the AI agent, so ask for a quote if you plan to use it.

On billing, Callbell's terms describe a fixed monthly price that may be billed quarterly, semi-annually or annually, and are governed by French law. If you use Callbell today, check which billing period you are on before switching platforms.

Callbell and HellouOne measure price differently: Callbell charges per agent and per channel account, and HellouOne charges per plan with agents and AI messages included. Compare with your number of agents, your channels and your real conversation volume. To estimate your Meta fees, use the WhatsApp pricing calculator, and look at HellouOne's plans or try the inbox and the AI agent for 7 days with no card.

AI agents and voice: what each one offers

The biggest difference is voice. HellouOne has AI voice agents that answer phone calls and run outbound call campaigns, with Colombian telephony included in the price, transfer to your team, and a summary and recording of every call. Plans run from USD 499 to USD 2,999 a month depending on minutes, and extra minutes are billed per second. They use the same AI agent, the same knowledge and the same inbox as WhatsApp and web chat. See the AI voice agents guide. We did not find AI voice agents on Callbell's site as of November 2026.

On text, both have AI agents. In HellouOne the AI agent replies first using your knowledge base and uses handover areas to pass the chat to the right person or team with the full history. From the Growth plan, AI classifications label each conversation by lead qualification and sentiment. We explain it in the WhatsApp AI agent guide.

Callbell describes an AI agent that serves customers on WhatsApp, Instagram, Messenger, Telegram, TikTok and web chat, sells, resolves and books, and hands the chat to the team with a summary when needed (see the sources).

Team inbox and channels

HellouOne assigns each conversation with round robin, priority or only to whoever is online, groups people into teams and sets five visibility levels per person. Private notes and @mentions keep the team coordinated, and reports show metrics per agent, per team and CSAT (CSAT from Growth). The inbox is used from the browser.

On channels, HellouOne includes WhatsApp and web chat on every plan, Telegram and Messenger from Growth, and Instagram and email from Scale; an additional channel costs USD 20 a month. HellouOne does not list TikTok among its channels.

On CRM, HellouOne syncs contacts and conversations both ways with HubSpot, Pipedrive, GoHighLevel and DataCRM, and deals move with the conversation in HubSpot and Pipedrive. It has 16 connectors, including Mercado Pago and Alegra. Developers get a public API and an MCP server, documented at one.hellou.ai/docs.

Callbell describes an inbox with automatic AI or manual routing, automatic assignment, labels, internal notes, funnels and per-agent reports, with Android and iOS apps. Its channels are WhatsApp, Instagram, Messenger, Telegram, TikTok and your website chat, and it offers Spanish-language support and a weekly webinar (see the sources).

How to move from Callbell to HellouOne without losing your number

You keep your WhatsApp number and your customers keep writing to the same contact. HellouOne connects the number to the official WhatsApp Business API and supports coexistence: the WhatsApp Business app and the team inbox work on the same number while the team settles in. Read how coexistence works and how to move your number to the API.

Plan the switch calmly: confirm with Callbell which billing period you are on and make the connection at a low-traffic time. These are the steps on the HellouOne side:

1. Create your HellouOne account. Try the inbox and the AI agent for 7 days, with no card, with 2 agents, 2 inboxes and 100 conversations (the WhatsApp channel connects when you pick a plan).
2. Pick your plan and connect your WhatsApp number. LIA guides you step by step; choose coexistence if you want to keep using the WhatsApp Business app.
3. Invite your team, group them into teams and set the assignment rules.
4. Load your knowledge base and turn on the AI agent with its handover areas.
5. If you use a CRM, connect HubSpot, Pipedrive, GoHighLevel or DataCRM.

When to choose HellouOne

HellouOne is a better fit in these cases:

• You want an AI agent included in the plan, with AI messages included and a clear cost per additional message (USD 30 per 1,000).
• You need voice: answering phone calls and launching call campaigns with AI voice agents and Colombian telephony, on the same platform as WhatsApp.
• You prefer to pay by the month in US dollars, with no lock-in and a 0% markup on Meta's fees.
• You want the same AI agent, the same knowledge base and the same inbox to handle WhatsApp, web chat and calls.
• You operate in Colombia and want Ley 2300 rules on collection calls and connectors such as Mercado Pago and Alegra.
• You need advanced routing, with priorities, teams, online-only assignment and five visibility levels.
• You want to keep using the WhatsApp Business app on the same number while the team moves to the inbox (coexistence).

If you are unsure, the 7-day free trial needs no card: try the inbox and the AI agent, and connect your WhatsApp number when you pick a plan. To see more of the product, read the WhatsApp team inbox guide.

When might Callbell be a better fit?

Callbell may be a better fit in these cases, based on what it publishes on its site (see the sources):

• You want TikTok and Telegram among your channels, next to WhatsApp and Instagram.
• You need Android and iOS apps for your team.
• You value an inbox that comes with its own sales funnels; HellouOne syncs contacts and conversations both ways with HubSpot, Pipedrive, GoHighLevel and DataCRM.
