Similar issues seem to apply to CallKey rebrands.

Tariffs have recently gone up on most of these. On mine (supplied from an early batch from 0044) this was unannounced and is now the same as Simazing tariffs despite a promise in April that it would stay lower, and I'm waiting for a response to a query about this.

It also isn't clear what renewal fee will be due. CallKey and 0044 refer queries back to the other (and 0044 is now selling CallBlue)

In terms of connectability and call quality, I doubt if there is any reason for any difference between all of them.

When you say Globalsim, note that there are two operations trading with this name; the rather longer established one in Germany was previously a UM reseller, and the recent UK one claims to have helped CallKey develop the roaming agreements for the last two years, but appeared many months later than other brands.
