SMS from your own SIM. One flat $10.
Agencies still pay Twilio per text for a number they already own.
Agencies still pay Twilio per text for a number they already own.
A phone sits in a drawer. The SIM is paid. The caller ID is the one clients already saved. And the CRM still routes SMS through a rented long-code and a second meter. That is the bill SMS Bridge is built to kill.
SMS Bridge pairs an Android phone and a SIM (or eSIM). Texts leave from that number into Go High Level or the Double My Leads inbox. We charge $10 per active SIM. We do not add a per-message meter. There is no A2P paperwork for BYOD SIM messaging. There is no $97 DML Platform seat.
If you want the product page, it is here: SMS Bridge. This post is the longer version: when it fits, when it does not, and how it sits next to WAsndr.
The bill you are actually paying
LC Phone and Twilio are fine products. They are also a second carrier. You pay the CRM vendor or Twilio for every segment, you register A2P if you send like an application, and you often give the lead a number they have never stored.
That makes sense when you need a provisioned long-code pool, high application-style throughput, or a number that is not tied to a physical SIM. It is a bad default when the business already has a local line, the volume is human, and the pain is the invoice, not the protocol.
SMS Bridge does not replace the carrier. You already pay that plan. We are the bridge from that SIM into the CRM thread.
What “your own SIM” means
BYOD here is literal. The number is yours. The SIM or eSIM lives in an Android. The grey-label app is named SMS Bridge, not Double My Leads. Your client installs a tool. They do not install our brand.
Leads text the local number they already have. Replies leave from that same caller ID. Sent, delivered, and failed report back into Go High Level Conversations or the DML inbox, so the thread does not lie.
Multi-SIM and eSIM are supported. One slot is $10 per active SIM / month. Cancel anytime.
Live in three steps
- Open a 7-day trial, or install SMS Bridge from the Go High Level Marketplace. You do not need the DML Platform plan.
- Install the grey-label SMS Bridge app on an Android with a SIM or eSIM. Scan to pair.
- Reply in GHL Conversations or the DML inbox. The text goes out on that SIM. Delivery states come back to the same thread.
After that, use the SMS channel in workflows the way you already do. We did not invent a new channel name for you to relearn.
What you actually get
- Your SIM, your caller ID. Not a rented long-code pool.
- $10 per active SIM / month. You already pay the carrier. We do not invent a second bill.
- Inside Go High Level. Send and receive in Conversations. Workflows keep using SMS.
- Grey-label Android app. Multi-SIM and eSIM. Clients install a tool, not our brand.
- Delivery back to the CRM. Sent, delivered, failed.
- No platform tax. SMS Bridge stands alone. The $97 DML Platform is optional if you also want inbox, WCA Groups, or white-label.
“Unlimited” here means we do not meter you. Your carrier plan, fair-use limits, and SMS compliance still apply. We will not pretend a $10 bridge deletes physics or carrier rules.
SMS Bridge vs WAsndr vs Twilio
Same family. Different job.
| SMS Bridge | WAsndr | LC Phone / Twilio | |
|---|---|---|---|
| Channel | SMS from a SIM | WhatsApp inside GHL | SMS from a provisioned number |
| Price we charge | $10 / active SIM | $19 / sub-account | Per-text + their seat |
| Number | Yours, on an Android | WhatsApp number you connect | Rented / registered |
| A2P for BYOD SIM | Not required | N/A (WhatsApp) | Usually yes if you send as an app |
| DML Platform $97 | Not required | Groups still need Platform | N/A |
| Who sees our brand | Grey-label app | Your GHL / DML setup | Their brand |
WAsndr is WhatsApp inside GHL. SMS Bridge is SMS from a SIM. If the lead lives on WhatsApp, use WAsndr. If the lead lives on SMS and you already own the line, use SMS Bridge. A lot of agencies will run both: WhatsApp where open rates win, SMS where the number in the phone book still wins.
Who this is for
GHL agencies. Accounts that already have a phone in the drawer and are tired of LC Phone / Twilio cost on low-to-mid volume sub-accounts. You keep Conversations and workflows. You drop the second meter.
Local businesses. Clinics, shops, and services that want SMS from the number people already saved. The caller ID is the point. A new long-code looks like spam. Their own line does not.
DML resellers. Add SMS next to WhatsApp. Same vendor, same trial, no extra platform seat. Grey-label means the client does not see Double My Leads on the phone.
Who should not use it
Skip SMS Bridge if you need iPhone as the bridge. The app is Android-only. The SIM lives in that Android.
Skip it if you need application-style bulk SMS, a rented number pool, or a setup where no physical device can stay online. That is still Twilio / LC Phone territory.
Skip it if you thought “unlimited” meant the carrier disappears. It does not. Throughput is the plan you already pay, plus fair-use and SMS rules.
Skip it if the job is WhatsApp. That is WAsndr.
Straight answers
Do I need DML Platform ($97)? No. SMS Bridge is a standalone layer. Buy a SIM slot and pair the phone.
Is messaging really unlimited? DML does not charge per text. Volume depends on your carrier plan, fair-use, and SMS rules. We do not invent a second meter.
Does it work on iPhone? The bridge app is Android-only.
Do I need A2P registration? Not for BYOD SIM messaging. You are sending as a regular phone, not as a registered application-to-person brand.
How is this different from WAsndr? WAsndr is WhatsApp inside GHL at $19 per sub-account. SMS Bridge is SMS from a SIM at $10. Same family, different channel.
What happens after the trial? 7 days free. No credit card. Then $10 per active SIM / month. Cancel anytime.
Put a SIM on the CRM
If the number is already yours, stop renting it back from a CPaaS.
