Every SMS, phone call, and voicemail you send through GoHighLevel runs on Twilio's carrier network underneath. What confuses most agencies is that there are two ways to use it: LC Phone, GoHighLevel's built-in phone system that wraps Twilio for you, or a direct Twilio account you connect yourself. The choice changes what you pay, who handles compliance, and whether you can rebill clients. This guide breaks down both setups, the real 2026 per-call and per-text costs, and the steps to get running without a surprise bill.
LC Phone vs Bringing Your Own Twilio
GoHighLevel gives you two telephony paths, and picking the right one first saves hours of rework. LC Phone (short for LeadConnector Phone) is the native option. GoHighLevel provisions the numbers, holds a prepaid wallet, and bills usage against it automatically. You never touch a Twilio dashboard. It is available on every plan, including the $97 Starter tier, and it is what most agencies should use.
Bringing your own Twilio account (often called BYOT) means you open a direct account with Twilio, buy numbers there, and connect it to GoHighLevel with your account SID and auth token. You manage billing, compliance, and number provisioning yourself. This path exists for high-volume senders and teams with specific carrier or international needs that LC Phone does not cover.
For most agencies and consultants, LC Phone wins on simplicity. You would only reach for direct Twilio at serious scale or when you need features LC Phone does not expose.
What GoHighLevel's Phone System Costs in 2026
Here is what LC Phone actually charges once you are live. These are passthrough rates, meaning GoHighLevel bills you close to Twilio's own carrier cost rather than adding its own margin on the usage itself.
A local US phone number rents for about $1.15 per month. Toll-free and international numbers cost more.
Outbound calls run about $0.021 per minute. That figure covers two legs Twilio bills separately: roughly $0.014 per minute for the outbound leg and $0.004 per minute for the dialer leg. Inbound calls are cheaper at about $0.0085 per minute.
Text messages are where the fine print matters. The base SMS rate is about $0.0079 per segment for US and Canada. But once mandatory carrier fees are added for a registered sender, the real all-in cost per segment typically lands between $0.013 and $0.018. MMS (picture messages) run about $0.02 per segment. Remember that a single long text can be billed as multiple segments, so a 320-character message costs roughly double a short one.
None of these are flat monthly fees. LC Phone is pure usage billing drawn from a prepaid wallet, so your bill scales directly with volume.
The A2P 10DLC Fees You Cannot Skip
Before LC Phone will send automated texts to US numbers, you must register for A2P 10DLC. This is a US carrier requirement, not a GoHighLevel upsell, and the fees pass straight through from The Campaign Registry with no markup.
Expect a one-time Standard Brand registration fee of about $24.50, which includes a small fast-track charge for approval in roughly three business days. Each campaign you submit carries a $15 vetting fee. On top of that, a recurring campaign fee of up to about $11 per month applies per approved campaign under Campaign Registry rules.
These charges are unavoidable if you send US SMS, and they are separate from your per-message costs. We covered the full flow in our A2P 10DLC registration guide, and you should complete it before you plan any texting campaign.
How to Set Up LC Phone in GoHighLevel
Setting up the native phone system takes only a few minutes. First, open Settings, then Phone Numbers inside your sub-account. If LC Phone is not already the active provider, GoHighLevel prompts you to enable it.
Second, add funds to your wallet under Settings, then Company Billing. LC Phone draws down from this prepaid balance, so it needs a positive amount before you can buy a number. Third, click Add Number, search by area code, and purchase a local number for about $1.15 per month.
Fourth, complete A2P 10DLC brand and campaign registration before sending any automated SMS. GoHighLevel will not let approved texting run until this clears. Fifth, set up auto-recharge so your wallet tops up automatically when the balance drops below a threshold you set. This is the single best way to avoid messages silently failing mid-campaign.
Once the wallet is funded and A2P is approved, calls and texts work across the CRM, workflows, and conversations without further configuration.
How to Connect Your Own Twilio Account
If you have decided direct Twilio is right for your volume, the connection is straightforward but shifts responsibility onto you. Create an account at Twilio and complete their identity verification, then purchase at least one phone number inside the Twilio console.
In GoHighLevel, go to Settings, then Phone Numbers, and choose the option to connect an existing Twilio account. Paste in your Twilio Account SID and Auth Token from the Twilio console dashboard. Handle A2P 10DLC registration inside Twilio directly rather than through GoHighLevel, since Twilio now owns that compliance layer for your numbers.
The tradeoff is clear. You get direct carrier billing and full access to Twilio's feature set, but you also own every compliance step, number purchase, and support ticket yourself. There is no prepaid wallet buffer and no GoHighLevel support team to escalate telephony problems to.
A Realistic Monthly Cost Example
Rates per minute feel abstract, so here is a concrete monthly estimate for a small agency running one active sub-account. Say you have one local number, make 500 minutes of outbound calls, receive 300 minutes of inbound, and send 4,000 SMS segments to registered contacts in a month.
The number rental is about $1.15. Outbound calls at $0.021 per minute come to roughly $10.50. Inbound at $0.0085 per minute is about $2.55. Texting is the big line: 4,000 segments at a realistic $0.015 all-in average is about $60. Add the recurring A2P campaign fee of up to $11 per month. That totals roughly $85 in usage on top of your plan fee.
Double the texting volume and your usage cost climbs to about $145. The takeaway: for most agencies, SMS volume rather than voice drives the phone bill, so model your texting first.
Common Costs Agencies Forget
A few charges surprise people on their first LC Phone bill. Segment math is the biggest one. Carriers count SMS in 160-character segments (or 70 for messages with emoji and special characters). A message that looks like one text can bill as two or three segments, so a chatty workflow multiplies faster than expected.
A2P fees are separate from message costs and recur monthly per campaign, so budget for them as a fixed line rather than a one-time setup charge. Failed messages can still incur carrier fees in some cases, which means a poorly targeted list wastes money on top of hurting deliverability. Finally, if you never enable auto-recharge, a drained wallet silently stops your texts and calls, which can look like a broken automation when it is really an empty balance.
Rebilling Clients for Phone Usage
If you resell GoHighLevel to clients, phone usage is a margin opportunity, but the rules changed. On the Agency Pro plan at $497 per month, you can rebill LC Phone usage to your sub-accounts at a markup you set, commonly 2x or 3x the underlying cost.
The important 2026 update: GoHighLevel no longer applies your markup to carrier fees and A2P 10DLC compliance charges. Those pass through to your client at cost. Your multiplier only applies to the base usage, not the regulatory fees layered on top. So if you quoted clients a flat 3x on everything, recheck your numbers, because your actual margin on a texting-heavy account will be lower than the headline multiplier suggests.
Rebilling is only available on Agency Pro. The $97 Starter and $297 Unlimited plans let you use LC Phone but not resell its usage at a markup.
LC Phone or Your Own Twilio: Which to Pick
For the vast majority of agencies, consultants, and single operators, LC Phone is the correct default. The prepaid wallet, one-click number provisioning, built-in A2P flow, and GoHighLevel support make it far less work, and the passthrough pricing is competitive with Twilio's own rates.
Direct Twilio makes sense in a narrow set of cases: very high message volume where small per-segment differences add up, specific international routing LC Phone does not support, or a requirement to keep telephony billing entirely separate from GoHighLevel. If none of those describe you, the added complexity is not worth it. If you are still deciding whether the platform as a whole fits your agency, our full GoHighLevel review covers pricing, features, and who it is built for.
The Bottom Line
GoHighLevel's phone system is Twilio under the hood, offered two ways. LC Phone wraps it in a prepaid wallet with passthrough pricing: roughly $1.15 per number each month, $0.021 per outbound minute, and $0.013 to $0.018 per registered SMS segment once carrier fees are counted. Add the one-time and monthly A2P 10DLC fees before you send a single automated text. Bringing your own Twilio account only pays off at high volume or for special routing needs. Start with LC Phone, fund the wallet, complete A2P registration, and turn on auto-recharge. That covers what most agencies need.
