Why this app? When you travel near country borders, your phone may automatically connect to a stronger cell tower across the border—even if you never left your country. This can quickly result in costly roaming fees. Manually toggling roaming is inconvenient and easy to forget.Roaming Borders automates the guardrails so you don’t have to. What it does Block roaming when you don’t want it: Select allowed countries; if your device connects outside that list, data traffic is blocked. Avoid surprise charges: Prevent accidental cross-border roaming near national frontiers. Simple presets or full control: Choose ready-made country presets or build your own list for upcoming trips. On-device only: Uses Android’s VpnService as a local firewall. No tunneling to servers. How it works Roaming Borders runs a lightweight, on-device VPN that filters traffic based on your current country. When your current country is not in your allow-list → block data traffic system-wide. When your current country is allowed → allow traffic as normal. When connected to Wi-Fi, the guard pauses automatically and resumes once Wi-Fi disconnects. Note on reboot: After restarting your phone, the guard re-enables after a short delay. To be extra safe, enable Airplane mode before restarting.

Displays a notification with current operator's name and in case of roaming it also shows the original SIM's operator name. If you swipe (dismiss) the notification, a new one will be displayed when a change in the conexion occurs. To remove the service from memory and avoid further notifications, just tap the notification.

Following SSTV modes are supported: Robot Modes: 36 & 72 PD Modes: 50, 90, 120, 160, 180, 240 & 290 Martin Modes: 1 & 2 Scottie Modes: 1, 2 & DX Wraase Mode: SC2-180 Old B/W or unsupported modes can be viewed in "Raw" mode. On detection of the calibration header of a supported mode, the resulting image will be automatically saved to the "Pictures" directory and can be seen in the Image gallery. With version 2, running the decoder in the background will not be supported anymore.

Android app implementing Roc sender and receiver. Work in progress! Features: receive sound from remote Roc-compatible sender and play to local audio device capture sound from apps or microphone and send to remote Roc-compatible receiver

Open-source team communication platform with channels, direct messaging, and video calls.

This app makes the shared storage of the device available via the Rsync protocol. Shared storage is what you can see in the "File Manager" app that usually comes with the device. This includes the 'DCIM' camera image folder as well as 'Downloads'. When the "start" button is pressed and the device has Wifi connectivity, the app will open a rsync server on a random port with a random tag ("module" in rsync parlance). It will display all necessary details on how to connect to that server while it is running, e.g. rsync://192.168.123.123:66671/abcdef/ Using a standard rsync client the server can then be interrogated and files moved back and forth, i.e. to and from the phone. The benefit is that the transfers can be driven from the client desktop, the keyboard and mouse interface of which making the process much more convenient. Note: This app has not been widely tested and should therefore be considered alpha quality.

Rumble is a completely off-the-grid application and delay-tolerant micro-blogging application that allows a device to connect, chat and share content (text and images) with other people around you. It doesn't require Internet to work and rely instead on Smartphone, Local Area Network (Bluetooth and Wifi) and human mobility to spread information. Using only the social fabric as an infrastructure, it makes Rumble suitable for use case where the Internet is either best to avoid (surveillance/censorship) or simply not available.

As Google strongly restricts the use of SMS permissions for applications in the Play-Store, S2MSP provides an API for third party applications to send and receive SMS to specific phone numbers via a secure SMS proxy.S2MSP acts like a local firewall for SMS communication.Each application that wants to send/receive SMS to a phone number can register itself on S2MSP. S2MSP asks the user for permission, whether the requesting application is allowed to send/receive SMS from and to the requested phone numbers or not.All SMS exchanged with third party applications are strongly encrypted.S2SMP itself requires SMS permissions (SEND_SMS and RECEIVE_SMS) from the Android system and will request these permissions upon startup. S2MSP does not need any other permissions. This ensures the integrity and security of S2MSP.The API to integrate a third party application with S2MSP is available in Maven-Central.

This app is meant for users that don't want to synchronize their contacts online, but want to keep them local to the phone. Though there is a problem, if you brick your phone, you might lose all your contacts. With this app, you will have a backup of your contacts stored on the SD card. You can take it out and import the contacts into your new phone.

SMS Filter can filter incoming SMS messages before they reach your inbox. You can filter by address, and optionally add parts that must occur in the message for it to be blocked. By default, SMS Filter will not delete incoming messages. You will get a silent status bar notification when SMS Filter has filtered an incoming message, which you can view by opening the notification or by opening the application. You can also tell SMS Filter to delete incoming messages, in which case it will happily do so for you. To do this, just turn off the 'Save messages' preference.

Transfer texts easily With this app, you an receive your SMS on all your devices. Bypass regional restrictions If a service in country A requires a phone number from country A, but your phone number is from country B. You ask a friend from country A to install this app and you will be able to receive SMS from the service in country B. However, since this is a pretty simple application, it can also serve other purposes. Features: - Can handle multiple redirections - Global activation toggle SMS Forward is free, open source and without ads. Warning: If someone is asking you to install SMS Forward, be careful: this could be a scam.

SMS Forwarding listens for incoming SMS text messages and conditionally forwards them to other numbers.

SMS Import / Export imports and exports SMS and MMS messages, call logs, contacts, and blocked numbers from and to (ND)JSON / ZIP files. (Contacts import and export are currently functional but considered experimental.) It does not require root. The primary author of SMS Import / Export is Thomas More. Others have contributed code and translations. The software is copyright 2021-2026, and is released under the GNU General Public License version 3 or later. SMS Import / Export is a sibling project to sms-db, a Linux tool to build an SQLite database out of collections of SMS and MMS messages in various formats. sms-db will hopefully eventually be able to import ZIP files created by SMS Import / Export, and to export its database to ZIP files that can be imported by SMS Import / Export.

This app is for you if: * You keep forgetting to send a birthday sms to someone * You have that friend who doesn't seem to know what an alarm is

SMS my GPS listens for incoming SMS text/data messages and conditionally sends an automatic reply containing GPS location data. The „trigger-word“ and white-listed sender phone number can be configured in the app.

Incoming SMS to URL forwarder will forward incoming SMS to a URL you specify: Set sender phone number or name and URL. It should match the number or name you see in the SMS messenger app. If you want to send any SMS to URL, use * (asterisk symbol) as a name. Every incoming SMS will be sent immediately to the provided URL. If the response code is not 2XX or the request ended with a connection error, the app will try to send again up to 10 times. The first retry will be after 10 seconds, later wait time will increase exponentially. If the phone is not connected to the internet, the app will wait for the connection before the next attempt. Optional extras: match senders with a regular expression, filter by message text, sign requests with HMAC-SHA-256, keep messages that failed to deliver for a manual retry, send a periodic heartbeat ping for monitoring, forward to local-network endpoints without internet, and back up / restore your forwarding rules as a JSON file.

SMS2Email forwards incoming SMS messages to a specified email address. This app is useful for users who need to access their SMS messages remotely.
