MyCRMSIM Review: Texting Without A2P in GoHighLevel?

Last updated: October 26, 2026

MyCRMSIM is a messaging gateway that sends texts from a phone you own. So your GoHighLevel sub-account can send SMS, iMessage, WhatsApp and RCS without renting an LC Phone or Twilio number. It skips A2P 10DLC paperwork, but it does not remove your consent and carrier obligations as a business sender.

This MyCRMSIM review covers how it works with GoHighLevel, what it costs today, where it genuinely helps, the compliance risks most reviews skip, and when registering A2P 10DLC is the safer choice for your clients.

What is MyCRMSIM?

MyCRMSIM is a bring-your-own-device texting service. An app on your Android phone or a Mac paired with an iPhone relays messages between your CRM and the phone’s SIM. Contacts see a normal text from your real mobile number instead of a message from a registered business line.

The company sells four channels, each tied to a device you connect yourself:

• SMS: an Android phone with an SMS-capable SIM or supported eSIM.
• iMessage: an iPhone plus a supported Mac, with automatic SMS fallback.
• WhatsApp: a WhatsApp account on a connected phone.
• RCS: a supported Android phone for richer Android messaging.

MyCRMSIM lists HighLevel, HubSpot, Salesforce, Zoho, Make, Zapier, an API and an MCP connection as integrations. It also offers its own CRM, pipelines, forms, chat widget and AI agents. But most GoHighLevel users buy it only as a texting channel for their existing sub-accounts.

How does MyCRMSIM work with GoHighLevel?

MyCRMSIM works with GoHighLevel by acting as the sending channel for a sub-account. Messages you send from the GHL Conversations inbox or a workflow go to the MyCRMSIM app on your connected phone. The app sends them through the SIM, and replies flow back into the same contact record.

In practice this changes three things compared with standard GHL texting:

• The number: texts come from the SIM’s mobile number, not an LC Phone or Twilio 10DLC number.
• The cost model: you pay a fixed monthly fee plus your phone plan, instead of per-segment SMS charges billed through your HighLevel wallet.
• The reliability chain: delivery now depends on a physical phone staying powered, online and running the app.

Your pipelines, opportunities, custom fields, tags and automations stay inside GoHighLevel. That is the main selling point for agencies: you keep the CRM and change only the pipe the texts travel through. If you want a refresher on how GHL bills its own messaging, our GoHighLevel SMS pricing guide breaks down the LC Phone costs you would be replacing.

How much does MyCRMSIM cost?

MyCRMSIM pricing, checked on its public pricing page in October 2026, starts at US$97 per month for the SMS plan. That plan covers up to 10 sub-accounts with one SIM each. iMessage, WhatsApp and RCS each cost US$29 per line per month, dropping to US$19 per line from 11 lines.

Three costs are not in that table, and buyers often forget them:

• The phone plan: every SIM needs its own unlimited-text mobile plan.
• The hardware: an Android phone per SMS line, or an iPhone plus a Mac for iMessage.
• Your time: someone has to keep each device charged, updated and connected.

MyCRMSIM advertises a 30-day money-back guarantee. Its refund policy also says refunds are not available for accounts found in violation of its terms, including spam or prohibited messaging activity. So read the terms before you test it at volume.

Does MyCRMSIM remove the need for A2P 10DLC?

MyCRMSIM removes the A2P 10DLC registration step, because the texts never touch a 10DLC number registered with The Campaign Registry (TCR). It does not change who the sender is. Under the CTIA Messaging Principles, a business texting its leads is a non-consumer sender, whatever device it uses.

The CTIA Messaging Principles and Best Practices (May 2023) state that if the message sender is a business, or someone acting on behalf of a business, the messaging is considered non-consumer. The older edition called the same split “Consumer (P2P)” and “Non-Consumer (A2P)”, and non-consumers are expected to get consent before they text anyone.

So the honest summary is:

• What you skip: brand registration, campaign registration, carrier vetting and the wait for approval.
• What you keep: the duty to have consent, honor STOP requests, and follow the TCPA and state texting laws.
• What you add: exposure to your mobile carrier’s consumer-plan rules, which generally prohibit spam and mass automated messaging.

MyCRMSIM’s own terms say the same thing in its language: no messages to people who have not opted in, no spamming, a clear automated opt-out, and compliance with SMS rules in your country. The responsibility stays with you. For a plain-English primer on the registration route, A2P Ready explains what A2P 10DLC is and who needs it.

What are the compliance risks of SIM-based texting?

The compliance risks of SIM-based texting are carrier enforcement, legal liability and lost data. Carriers can filter or suspend a personal line that behaves like bulk business traffic. The TCPA applies to marketing texts regardless of channel, and a suspended SIM can take its conversation history with it.

Carrier enforcement on personal lines

Personal mobile plans are built for people texting people. When one line sends many near-identical messages to contacts who rarely reply, carriers can flag it as spam, throttle it or cut the line. MyCRMSIM itself tells users to stay within carrier fair use and to use drip mode for large sends.

TCPA, consent and opt-outs

The TCPA and state “mini-TCPA” laws care about consent and content, not about whether your number was registered. A cold list texted from a SIM is the same legal problem as a cold list texted from a 10DLC number, only with fewer guardrails. Make sure GoHighLevel’s DND and STOP handling still works through the new channel.

Regulated industries and records

Healthcare, insurance and financial clients have record-keeping and privacy rules on top of texting law. Before routing their texts through a phone in someone’s drawer, read our guides to HIPAA compliance in GoHighLevel and text message archiving for SEC and FINRA.

MyCRMSIM vs A2P 10DLC in GoHighLevel

MyCRMSIM vs A2P 10DLC comes down to speed versus durability. MyCRMSIM gets a sub-account texting within a day with flat pricing. A registered 10DLC number through LC Phone takes days to approve but gives carrier-sanctioned throughput that survives growth and audits.

If you go the registered route, our walkthrough of GoHighLevel A2P 10DLC registration covers the brand and campaign details that most often cause rejections, such as a legal name that does not match the EIN record.

Who should use MyCRMSIM, and who should not?

MyCRMSIM suits solo operators and small teams who send personal, one-to-one follow-up to people who already know them. It is a poor fit for agencies running bulk campaigns, cold outreach or database reactivation blasts across many clients. Those patterns are exactly what carriers filter on personal lines.

Reasonable use cases:

• A real estate agent or broker replying to inbound leads from their own mobile number.
• A coach sending appointment reminders to a small client base that opted in.
• A sales rep who wants iMessage blue bubbles for warm, conversational follow-up.
• A business waiting on A2P approval that needs to answer existing customers in the meantime.

Use cases we would avoid:

• Texting purchased or scraped lists, which breaks MyCRMSIM’s terms as well as the TCPA.
• Large “reactivation” sends to old contacts with unclear consent.
• White-label resale to dozens of client sub-accounts that you cannot supervise.
• Regulated clients that need archived, auditable message records.

If blue-bubble delivery is the real goal, compare this with the other add-ons in our GoHighLevel iMessage options guide, since the iMessage line here carries a 50-unique-contacts-per-day limit.

What to check before connecting MyCRMSIM to a sub-account

Before connecting MyCRMSIM to a GoHighLevel sub-account, confirm consent records, opt-out handling, device ownership and a fallback plan. These four checks decide whether a SIM-based line is a useful extra channel or a liability that disappears the day the carrier suspends the number.

1. Consent: every contact you will text has a recorded opt-in that names your business.
2. Opt-out: a STOP reply sets DND on the contact in GoHighLevel, and your workflows respect it.
3. Device ownership: the phone and SIM belong to the business, not an employee who might leave.
4. Carrier plan: you have read your plan’s acceptable-use terms for automated messaging.
5. Volume: sends are spaced out, and you are not using the line for bulk marketing.
6. Fallback: you know which channel takes over if the device goes offline or the line is cut.
7. Records: conversation history lives in GoHighLevel, not only on the phone.

None of these steps require deep technical work, but skipping them is how agencies end up rebuilding messaging under pressure after a line goes dark.

MyCRMSIM review verdict

MyCRMSIM is a legitimate tool for low-volume, personal texting from GoHighLevel, with clear flat pricing and genuinely fast setup. It is not a way around texting compliance. It should not replace A2P 10DLC registration for any business that sends marketing or reminders at scale.

Our recommendation for agencies: register A2P 10DLC for every client sub-account that sends business texts, and treat a SIM-based line as an optional extra for personal follow-up, never as the foundation.

Tired of A2P rejections pushing you toward workarounds?

A2P rejections push many GoHighLevel users toward SIM workarounds. Yet most rejections come from fixable issues. The usual ones are a legal name that does not match the EIN, a website without SMS consent language, or vague sample messages. Fixing those once gives a client durable, registered texting.

Our team does done-for-you GoHighLevel setup, including the phone system, A2P 10DLC brand and campaign details, opt-in forms and the workflows that respect DND. If an earlier build left the account messy, we start with a review and give you a fixed quote before any work begins.

Frequently Asked Questions

Is MyCRMSIM legit?

MyCRMSIM is a real company with public pricing, terms of service and a 30-day refund policy, and it lists HighLevel among its integrations. Being legitimate software does not make every use lawful, though. You are still responsible for consent, opt-outs and your carrier’s acceptable-use rules for every text you send through it.

Does MyCRMSIM work with GoHighLevel?

Yes. MyCRMSIM lists HighLevel as an integration, and it acts as the sending channel for a sub-account. Texts sent from the GoHighLevel Conversations inbox or workflows leave through your connected phone’s SIM, and replies return to the same contact record. So pipelines and automations stay in GHL.

Is texting without A2P registration legal?

A2P 10DLC registration is a carrier requirement for business texting on 10DLC numbers, not a law in itself. Laws like the TCPA still apply to every business text, whatever the channel. Sending from a personal SIM avoids the registration step but can break your carrier’s consumer-plan terms if you send bulk or automated business messages.

How much is MyCRMSIM per month?

MyCRMSIM’s SMS plan costs US$97 per month for up to 10 sub-accounts with one SIM each, or US$970 a year. iMessage, WhatsApp and RCS lines cost US$29 per line per month, or US$19 per line from 11 lines. Your phone plans and devices are extra.

Can a carrier block a number used with MyCRMSIM?

Yes. Because MyCRMSIM sends through a normal mobile line, that line is governed by your carrier’s consumer terms. If it behaves like bulk business traffic, such as many identical messages to people who rarely reply, the carrier can filter, throttle or suspend it, which also stops the connected GoHighLevel sub-account from texting.

Should agencies use MyCRMSIM or register A2P 10DLC?

Agencies should register A2P 10DLC for every client that sends business texts. This is because registered numbers are the channel carriers expect for that traffic and they do not depend on a phone staying online. A SIM-based line can be an extra channel for personal, one-to-one follow-up, but it should not carry campaigns.
