Dwish - Bulk SMS Sender

Dwish is the productivity SMS app for executives: the bulk SMS sender for the founder, sales lead, operations manager or event organiser who owns the follow-up and currently sends the same message ninety times by hand.

Import the list. Write the message once, with each recipient's own name and details in it. Send. Dwish does the ninety sends from your own SIM while you get on with the day.

WRITE ONCE, PERSONALISED FOR EVERYONE
• Merge fields — {name}, {firstName}, {phone} and any column your own file carries
• Fallbacks, so a blank cell reads "Hi there" rather than "Hi {name}"
• A live preview of the real merged message, against a real recipient
• Live GSM-7 / UCS-2 segment count on the merged text, so a campaign holds no surprises
• Saved templates for the message you send every week

YOUR LIST, FROM WHEREVER IT LIVES
• Excel (.xlsx / .xls), CSV, VCF and the device address book
• Headers matched against the spellings real exports use — phone, mobile, msisdn, contact number — instead of demanding an exact template
• Every extra column preserved and usable as a merge field
• Numbers normalised to international format against your SIM's country
• Every unusable row reported individually, with the reason

SENDING THAT FINISHES WITHOUT YOU WATCHING
• Sends through your own SIM with the phone's own SMS allowance — no gateway account, no per-message charge from us, no system composer, no per-message tap
• Dual-SIM devices choose which subscription sends
• A durable queue survives the app being backgrounded, swiped away or the device restarting, and shows progress in a notification with a Stop action
• Configurable pacing between messages and between batches, to stay inside carrier rate limits
• Automatic retry with backoff for transient failures; permanent failures reported at once rather than retried forever
• Schedule a campaign for the hour it should land

KNOW WHAT ACTUALLY ARRIVED
• Pre-flight review: recipient count, total segments, sending SIM, estimated duration and every rejected number, before anything is queued
• Live per-campaign counts as it sends
• Full history with a per-message log, including the telephony error behind each failure, and one-tap retry for the failed ones only
• Real send results plus carrier delivery reports when the network supplies them

REPLIES IN THE SAME PLACE
• A threaded inbox and conversation view, so an answer to a campaign is not something you find in another app
• An opt-out list every campaign honours, and duplicate recipients dropped automatically

PRIVATE BY CONSTRUCTION
Your contacts, templates and campaign history stay on the device, in local storage. Messages go out over your own carrier plan. Nothing is uploaded to a server of ours — there is no account to create and no list to hand over.

REQUIREMENTS AND HONEST LIMITS
• Android only. Sending silently through a chosen SIM has no equivalent on iOS.
• Standard SMS rates from your carrier apply to every message sent.
• Dwish sends text (SMS). It is not a marketing gateway and does not buy numbers for you: you bring the list, and you are responsible for having consent to message it and for honouring opt-outs.

Made for people whose time costs more than the evening they are about to spend on their thumbs.

QUESTIONS PEOPLE ASK BEFORE INSTALLING

Does Dwish need an internet connection?
No. There is no server and the app makes no network requests of its own — campaigns go out over your carrier's SMS channel, not the internet.

Do I need a gateway account?
No. Dwish charges nothing per message and there is nothing to sign up for; your carrier's own SMS rates apply.

Can I send a mass text from a spreadsheet?
Yes. Import .xlsx, .xls, CSV or VCF, or the phone's address book, and every row becomes its own personalised message.

Does it keep sending if I close the app?
Yes. The queue is written to storage before sending begins, so a campaign carries on while you use the phone and resumes after a restart.
