myCRMSIM, from myCRMSIM Technologies LLC (Wyoming) and myCRMSIM Limited (Hong Kong), connects devices you own to your CRM. iMessage runs on your iPhone plus a Mac (or a rented cloud Mac) running the myCRMSIM app; SMS and RCS run on an Android phone with a SIM; WhatsApp uses your own account. Its integrations and setup guides center on HighLevel. The company says it was founded in 2023 by Gary Capps.
iMessage, WhatsApp and RCS each cost $29 a month per line for 1 to 10 lines and $19 a month per line for 11 or more, or $290 per line per year. SMS starts at $970 a year for up to 10 sub-accounts. There are no per-message fees. You also pay for your own iPhone, Mac and phone plans. There is no free trial, but a 30-day money-back guarantee is offered.
Both offer iMessage with SMS fallback, group chats and flat pricing. Linq runs managed lines for you and documents RCS fallback, tapbacks, polls, SDKs, signed webhooks, an MCP server and SOC 2 Type II, from $260 a month on Pro. myCRMSIM costs less per line but needs your own iPhone and Mac, recommends 50 new contacts a day per Apple ID, and its API caps sends at 30 messages per 15 minutes per workspace.
HighLevel agencies and small businesses that already have iPhones, Macs and SIMs and want low fixed costs.
myCRMSIM supports 29 of the 77 features compared on Linq Alternatives.
