Short answer: The best Google Voice alternative depends on which Google Voice limitation actually bothers you. If it is the Gmail-account requirement, pick an app that lets you sign up with just a phone or email. If it is shaky international calling, group MMS, or call recording, weigh TextNow, a VoIP carrier like Line2, or a dedicated second-line app such as Text Call against those exact features — not against a generic "best app" list.
Most "Google Voice alternative" roundups score apps on price and call quality, then stop. That misses the point. People leave Google Voice for specific reasons: they don't want to attach a number to a Google Account, the number is hard to move later, group texts arrive broken, or international rates are unclear. So this comparison scores alternatives on the things Google Voice users complain about, not on a marketing checklist. Where our own app, Text Call, fits is disclosed plainly below — this is a comparison, not a veiled ad.
The five criteria that actually push people off Google Voice
I built the scoring around five recurring complaints, each tied to a behavior you can verify yourself rather than a number I'd have to invent:
- Portability — can you move the number out later, and how painful is it? Google Voice's own support pages confirm you must sign in with the registering Google Account, then "unlock" the number before another carrier can port it, and unlocking carries a fee in some cases (Google Voice Help, "Port your Google Voice number," checked June 2026).
- No-Gmail signup — can you get a number without tying it to a Google Account at all?
- International calling — are outbound international calls supported, and are rates published clearly?
- MMS and group texts — do picture messages and group threads work reliably, the single most common Google Voice texting gripe?
- Call recording — is it built in, and does the app surface the consent rules?
One honest caveat up front: I have not run a 30-day side-by-side spam test or a stopwatch on setup times, and you should distrust any roundup that quotes those as hard measurements without showing its method. The scores below are qualitative, drawn from each vendor's official pricing and feature pages plus App Store and Google Play listing data. Treat them as a map of where to look, then confirm the cells that matter to you.
The comparison matrix
Scoring is simple and disclosed: Strong means the feature is a documented, first-class part of the product; Limited means it exists with conditions, regional gaps, or a paywall; Weak/None means it is unsupported or a known sore spot. "Free tier?" reflects whether you can get a working number without paying.
| App | No-Gmail signup | Portability (move number out) | International calling | MMS / group texts | Call recording | Free tier? |
|---|---|---|---|---|---|---|
| Google Voice (baseline) | Weak/None — needs a Google Account | Limited — unlock + possible fee, US-centric | Limited — paid per-minute rates | Limited — long-standing group MMS complaints | Limited — incoming calls only, on by key press | Yes (US personal) |
| TextNow | Strong — email/phone signup | Check before relying on it | Limited — add-on / international plan | Strong — picture + group messaging | Weak/None natively | Yes (ad-supported) |
| Line (LINE app) | Strong — phone-based account | Not a portable phone number — it's an app-ID line | Strong — app-to-app worldwide; PSTN calling is separate | Strong — within the app's own network | Weak/None | Yes (app-to-app) |
| Line2 (VoIP business line) | Strong — email signup | Limited — VoIP port-out varies by plan | Limited — included/added depending on plan | Strong — MMS supported | Limited — paid feature on higher tiers | No — paid subscription |
| Text Call (our app) | Strong — no Google Account needed | Check current terms in-app before relying on it | Limited — supported where credit/plan covers it | Strong — picture and group texting | Limited — where the law and plan allow | Trial / credit-based |
A few cells deliberately say "check before relying on it" instead of a confident yes. Portability for any VoIP or app-based number is the cell most likely to change with a vendor's terms, and it is the one that strands people. I would rather send you to verify it than print a claim that ages badly.
Claim: Not every "second number" is portable, and Line (the LINE messaging app) is not a phone number you can move at all.
Evidence: LINE's account is tied to an app ID and is built for app-to-app calls and chats; PSTN dialing is a separate paid feature, per its store listing and help pages.
Limit: This does not mean LINE is worse — for free international app-to-app calls it is strong. It means it solves a different problem than a portable US line.
Action: If you need a number that survives leaving the app, rule out app-ID-only services before you commit.
The method: how to test "will this VoIP number be accepted?" yourself
The complaint no comparison table can answer for you is whether a given service's number will be accepted where you need it — by your bank's 2FA, a delivery app, or a verification SMS. App-assigned VoIP numbers are sometimes rejected by those systems, and the rules change quietly. Rather than assert which services pass, here is a reproducible check you can run in ten minutes before you depend on the number:
- Get the number, then trigger a low-stakes verification first. Use the new number to sign up for a free, disposable account somewhere you don't care about — not your bank. See whether the SMS or voice code arrives.
- Test the one service you actually need it for, in "add a number" mode. Add the new number as a secondary contact method before removing your old one. If the code never arrives, that service is blocking VoIP numbers, and you've lost nothing.
- Check inbound from a normal cell phone. Have a friend text and call the new number, including a picture message, to confirm MMS and group threads actually land.
- Log the result with a date. "Service X accepted the number on 2026-06-03" is worth more than any roundup, because acceptance lists go stale fast.
This is the honest version of "we tested the apps": a procedure you control, with your services, on your date. Your results are the only ones that count for your use case.
A real limitation everyone skips: 911 and outages
Second-number apps run over the internet, and that changes what happens in an emergency. The U.S. FCC's consumer guidance on VoIP and 911 is explicit: a VoIP 911 call may connect but fail to transmit your phone number or location automatically, you may need to register and update your physical location with the provider, and the service may not work at all during a power outage or internet failure (FCC, "VoIP and 911 Service," checked June 2026). Keep a real mobile line for emergencies. A second-number app is for the calls and texts you choose to make — not for dialing 911 from a dead Wi-Fi router.
Who should pick which: a decision tree
Run down these in order and stop at the first match.
- You mainly want free app-to-app calls to friends or family abroad, same app on both ends? → LINE. It is built for that and costs nothing app-to-app. It is not a portable phone number, so don't expect to move it.
- You want a free US texting-and-calling number and group MMS matters most? → TextNow. The free, ad-supported tier covers everyday texting and picture/group messages well; confirm international and recording needs separately.
- You're running a small business and want a polished business line with voicemail and MMS, and you'll pay for it? → Line2. It is subscription-only but aimed at exactly that, with recording on higher tiers.
- Your top reason for leaving is "I don't want a number attached to my Google Account," and you want a clean second line for selling online, dating, or a side gig? → A dedicated second-line app like Text Call, made by Codebaker, fits here: no Google Account required, picture and group texting, on a credit-based plan. Verify portability and any recording rules in-app first.
- You only need to send the occasional scanned page or fax, not a phone line at all? → You're looking for the wrong tool category; a document utility such as Fax Scan handles that without a second number.
Notice none of these is "the best app, period." Google Voice itself is still a fine pick if you live inside the Google ecosystem and don't mind the account link — the matrix only flags where it frustrates people enough to switch.
FAQ
What is the best Google Voice alternative if I don't want a Gmail account?
Pick an app whose signup uses a phone number or email rather than a Google Account. TextNow, Line2, and Text Call all create a number without tying it to Gmail. Google Voice, by contrast, requires a Google Account to register and to later port the number out, per Google's own support pages — which is exactly the friction many people are trying to avoid.
Can I keep my number if I leave the app later?
Sometimes, but never assume it. Portability for VoIP and app-based numbers varies by provider and plan, and some app-ID services (like LINE) aren't a movable phone number at all. Before you give the number out widely, check the provider's current port-out terms in writing. Google Voice, for example, requires you to unlock the number first, which can carry a fee.
Do these apps support international calling?
It depends on the type. Apps like LINE offer free app-to-app calls worldwide but charge separately for calling regular phone numbers abroad. Number-based services (TextNow, Line2, Text Call) typically support outbound international calls through credit or a plan, with per-minute rates. Always check the destination rate on the vendor's pricing page before a long call.
Can I record calls on a second-number app?
Some apps include recording, usually on paid tiers, and Google Voice records incoming calls only. The bigger issue is legality: consent rules differ by state and country, and several U.S. states require all parties to agree. Treat any built-in recording feature as something you must use within your local law, not as a green light.
Can I use a second-number app to call 911?
Don't rely on it. The FCC warns that VoIP 911 calls may not transmit your location, may require you to register your address, and won't work during a power or internet outage. Keep a standard mobile line for emergencies and use the app for routine calls and texts.
What I'd do
Start from your actual complaint, not the leaderboard. Write down the one Google Voice limitation that pushed you to look — the Gmail link, broken group texts, fuzzy international rates, no recording — then read only that column in the matrix above. Get the candidate number, run the ten-minute acceptance test against the one service you truly need, and keep a real cell line for 911. If your reason is "no Google Account, clean second line for a side gig," try Text Call from Codebaker and confirm its current porting and recording terms in-app before you build anything around the number.
