Why SUVO Uses Inbound-Only Traffic
An introduction to inbound-only channel operations and availability monitoring. At SUVO, an approved device receives calls and messages and does not originate them. Here’s what that means in practice, what stays your responsibility, and how to keep your channels available, since availability is what the fixed daily rate is for.
What “inbound-only” means
SUVO is a B2B platform for inbound Voice + SMS channel hosting. When your GoIP gateway is connected to SUVO, approved channels are used in one direction only:
- They receive voice calls and SMS from SUVO’s business clients.
- They do not originate calls or messages. SUVO does not place outgoing calls or send SMS from your cards.
Your hardware and SIM cards stay with you, at your location. SUVO handles routing, quality monitoring, and client management for authorized inbound services; your responsibility is to keep the approved device and channels available.
How a call or SMS reaches your channel
- A SUVO business client sends a call or an SMS to the number of a SIM card in your gateway.
- It travels over the mobile network like any call or text to a mobile number.
- Your GoIP receives it on the SIM. Voice routing uses the approved SIP configuration; inbound SMS forwarding requires support to confirm an interface compatible with your exact model and firmware.
- SUVO delivers it to the client.
At no point does your channel originate a call or a message on SUVO’s behalf.
What it means for you as a partner
No outgoing usage for SUVO
Because SUVO does not place outgoing calls or send SMS through your cards, your balance isn’t spent on outgoing usage for SUVO. Many plans don’t charge for receiving calls and SMS in the home network, but plans differ, so check the terms of yours (for example, for roaming).
Fewer settings to manage
There are no outgoing routes or dial plans to configure for SUVO. Your setup is: register each port, keep the cards online. See How to Connect Your GoIP Gateway.
A fixed daily rate for availability, not volume
You earn a fixed daily rate for each card that stays available (≥95% uptime/day), whether it receives many calls that day or few. Rates currently range from roughly $0.45–0.90 per card per day, depending on country and demand. A day below the 95% availability threshold receives no provider payout. These figures are estimates, not guaranteed.
Estimating your earnings
Because the rate depends on how many cards you keep available rather than on traffic you can’t control, you can estimate in advance: available cards × daily rate × 30 for a 30-day month. For example, 8 cards at $0.45/day equal about $108 for a 30-day month before days that do not meet the availability threshold. The earnings calculator on the SUVO homepage uses the current rate tiers by country.
Validation and payout requests
Every new channel goes through a 5-day validation: it is tested for voice quality, SMS delivery rate, and connection stability. Passing confirms that the channel can enter the active pool; it does not increase the fixed daily rate. Keep the device online while the review is in progress. Weekly payout requests start from $10 in USDT or USDC and are reviewed manually while automatic weekly payouts are planned.
How this differs from outbound gateway use
GoIP gateways are general-purpose VoIP–mobile gateways. A common use is outbound: a VoIP system sends calls out through the gateway, and the SIM cards dial mobile or landline numbers. In that setup the SIM places the calls and pays for them from its balance or bundle, and earnings usually depend on traffic volume.
SUVO does not work this way. Approved channels receive calls and messages and do not originate them, and your rate doesn’t depend on traffic volume. In short:
| Outbound gateway use | SUVO (inbound-only) | |
|---|---|---|
| Direction | SIM places outgoing calls / SMS | Channel receives calls / SMS only |
| Cost to the SIM | Outgoing usage charged to balance or bundle | No outgoing usage for SUVO |
| What you’re paid for | Usually traffic volume | Availability: a fixed daily rate per card (≥95% uptime/day) |
| Setup for the platform | Outgoing routes, dial plans, limits | SIP registration for each port, cards online |
This describes how the two models differ. It is not a statement about how any carrier will treat a particular card; see the next section.
What stays your responsibility
Inbound-only describes how SUVO uses your channels. It doesn’t change your own obligations:
- Carrier terms. Use your SIM cards in line with your mobile operator’s terms of service. Terms differ between operators and plans; read yours.
- Local requirements. Requirements vary by country and carrier. Use only authorized infrastructure and consult qualified local advice where needed. Contact support to check regional availability.
- Your plans and hardware. Keeping plans active and the gateway running is up to you, and it’s also what your earnings depend on.
Availability depends on carrier rules, network conditions, and local compliance requirements. SUVO cannot promise how a carrier will treat any card. If you have questions about your specific plan, ask your operator.
Availability monitoring
SUVO runs inbound-only channels with platform monitoring, and your dashboard shows the status and earnings recorded for each channel. A card needs to be available at least 95% of the day, which leaves roughly 72 minutes of downtime per day. Good habits on your side:
Power
- Use the original power adapter.
- Put the gateway and your router on a UPS if power cuts happen where you are.
- Label the plug so nobody unplugs it by accident.
Signal
- Keep all antennas attached and place the gateway where reception is good.
- Check per-channel signal (RSSI) in the GoIP web admin under Status › Summary after installation and after moving the device.
- Make sure the network technology your model uses (for example 2G on classic GoIP models) is still available from your operator.
Network
- Bandwidth depends on the codec and number of simultaneous calls. Ask support to confirm the requirement for your approved channel configuration; a wired connection is strongly preferred over WiFi.
- Avoid chaining two routers (double NAT) where possible.
- If your connection drops often, fix that first. It affects every card at once.
Daily checks
- Check channel status in your SUVO dashboard every day and fix any offline card the same day.
- For a closer look, the GoIP’s Status › Summary page shows, per channel, whether the SIM is recognized, registered to the mobile network and registered to SUVO (SIM / GSM / VoIP).
Keeping plans active
- Track each card’s plan expiry or renewal date and renew on time. A lapsed plan means an offline card.
- If a card has a PIN, keep it recorded; after a power cycle the card needs the PIN to register.
- Before swapping a SIM, switch off power to its slot (see setup step 6).
Quick answers
Will SUVO send SMS or make calls from my card?
No. Approved channels receive calls and messages and do not originate them.
Do I earn more if my card receives more calls?
No. You earn a fixed daily rate per available card (≥95% uptime/day). Traffic volume doesn’t change it, and passing validation doesn’t increase it either.
Does inbound-only mean my channels will always stay available?
No one can promise that. Availability depends on carrier rules, network conditions, and local compliance requirements. How you use your SIM cards remains subject to your operator’s terms, which you’re responsible for following.
How many cards should I connect?
As many as you can keep reliably available. See GoIP 8 vs GoIP 32: Which Device Fits You?.
