without searching the internet. imagine you have no internet. do you have any computer with a modem? do you know anyone that does? can you get access to one? do you have dialup software? do you have a dial up international internet provider? can you find one? remember you need to do all of this without the internet. can you sign up for one? would they allow you to pay for it from Iran? the best time to get ready is before SHTF
If you’re using the circuit-switched mobile phone calls it’s unlikely you will be able to negotiate that; GSM compression is optimised for voice and not data.
If you have a phone or cellular dongle with a serial interface you might be able to initiate a “data” call which gives you a modem-like link at speeds much higher than running an actual modem on the audio path. Note that this kind of non-standard usage will stand out like a sore thumb so might not be advisable.
