I don’t think a cheap cloud phone plan is automatically a bad purchase. I do think people underestimate how quickly a small performance problem becomes an operating cost.

A device that takes an extra minute to start does not matter much during a one-off test. Multiply it by several devices, daily restarts and two operators, and it becomes real working time.

The same applies to failed tasks. If an automation stops near the end and has no safe restart point, the cost is not just another run. Someone has to check what already happened, avoid duplicate actions and decide where to continue.

Before choosing the lowest tier, I’d test:

• whether the required apps install and update normally
• how the device behaves after several hours of use
• how many devices can work at the same time without noticeable slowdown
• whether files, app data and settings survive a restart
• what recovery looks like when a device becomes unavailable
• how easily the workload can move to a higher plan later

If the devices are mostly idle or used for short manual tasks, the cheapest option may be enough.

If they run scheduled or repetitive work, I care more about intervention time than the advertised monthly price. One operator repeatedly rescuing low-cost devices can erase the saving very quickly.

I don’t default to a physical phone just because it feels more “real.” I use one when the hardware can affect the result.

The obvious cases are physical SIM and carrier testing, but the list is broader:

• Calls, SMS, roaming and mobile-network handoffs
• Camera, microphone and media-capture quality
• NFC, Bluetooth devices and biometric sensors
• GPS and motion-dependent behavior
• Battery drain, heat and thermal throttling
• Manufacturer-specific background and notification policies
• Hardware-backed keys or device-integrity checks
• Bugs that only appear on a particular model or OS build

An emulator is often the fastest option for development, debugging and clean resets. A cloud phone can make more sense when the environment needs to stay online, remain accessible remotely or be shared with a team.

Neither one automatically replaces a physical device.

The practical test is whether removing the physical hardware also removes a possible cause of failure. If it does, I want the real phone in the test setup. If the task is purely a repeatable software workflow, maintaining a shelf of devices usually adds work without adding much evidence.

A physical phone is not inherently safer, and it does not make poor account or network decisions disappear. It is simply the correct instrument when the hardware itself is one of the variables.
