Quo vs Smrtphone.io (2026): which should you pick?

Pick Quo if

• Fits if you want a work number on your own phone, apart from your personal one
• Works for a few people sharing one sales or support line who need the same history

Look elsewhere if

• Tight if you're on Starter and want a phone menu or call transfers, as those need Business
• Not for you if you call abroad a lot, since calls outside the US and Canada are billed per minute
• Pricey if Sona answers lots of calls, as each one past the plan's credits costs $0.45 to $1.00
• Watch out: US texting needs carrier registration, $19.50 once plus $1.50 to $3 a month
• Pricey if you pay monthly, at $19 for Starter and $33 for Business, or need extra numbers at $5 each

Pick Smrtphone.io if

• Works for sales teams that want calls and texts logged to a CRM

Look elsewhere if

• Pricey if you go unlimited: $83 a seat, with the FAQ giving 2,500 minutes and texts
• Tight if you need warm transfers or listening in: the $15 Advanced Calling add-on
• Watch out: extra numbers cost $2 to $5 a month, and text registration help is $97
• Watch out: the dialer, AI agents and support plans are priced separately
• Not for you if you use HubSpot, which is listed as coming soon
